StoreKit 2 Fails to Load Subscription Products
We are experiencing a critical issue where StoreKit 2 is returning empty products when using Product.products(for:), specifically on devices running iOS 18.4.

 This issue does not occur on iOS 18.3 or earlier.

 Steps:

 Created a subscription product (e.g. "upm1") in App Store Connect
 Confirmed the product is active, localised, and part of a valid subscription group
 Call the following Swift code using StoreKit 2:
 Task { do { let products = try await Product.products(for: ["upm1"]) print(products) } catch { print("Error: (error)") } } 4. Result: products is an empty list.

 This regression is blocking subscription testing on iOS 18.4. 

 Kindly someone please advise on a potential fix or workaround.

How to change promotional image of in-app purchase
My apps stuck on review stage. Reason of it is Guideline 2.3.2 - Performance - Accurate Metadata We noticed that your promotional image to be displayed on the App Store does not sufficiently represent the associated promoted in-app purchase. Specifically, we found the following issue with your promotional image: – Your promotional image is the same as your app’s icon. The problem is i can't change this image. My subscription is still in 'in review' stage and I don't have option like delete image or change image. I replied to the review explaining that I cannot change it as long as the subscription is under review, but I haven’t received any meaningful reply, except that I need to change promotion image to be eligible for further review(which i cant do because i haven't option to change this image). Has anyone had such a problem before?

StoreKit returning 0 products (IAPError: storekit_no_response)
Hi everyone, I’m facing an issue where StoreKit is returning 0 products from the App Store, even though my auto-renewable subscriptions are approved in App Store Connect. When calling queryProductDetails using Flutter’s in_app_purchase package (which uses StoreKit under the hood), StoreKit reports success but returns an empty list. The logs show the following error: IAPError(code: storekit_no_response, source: app_store, message: "StoreKit: Failed to get response from platform.") InAppPurchase.isAvailable() returns true, but no product details are received. Already verified: • Subscriptions are approved in App Store Connect • Product identifiers in the app match those in App Store Connect exactly • In-App Purchase capability is enabled in Xcode • Paid Applications Agreement, banking, and tax details are active and complete • Using the latest version of the Flutter in_app_purchase package StoreKit should normally return the list of available products in the production environment, but it consistently returns an empty array along with the “storekit_no_response” error. Has anyone else encountered this issue or found any potential causes for StoreKit failing to return products in the production environment? Any insights would be greatly appreciated. Thank you.

Inconsistent behavior with transactionId and appAccountToken in iOS Sandbox purchases (StoreKit1 & StoreKit2)
Hi, I'm reaching out to report a recurring issue with in-app purchases on iOS that seems to be related to Apple’s transaction handling — not to third-party libraries. In my Flutter application, I use both StoreKit2 and StoreKit1 (for comparison) via different packages, including the official in_app_purchase package. However, in both cases, I’m experiencing unexpected reuse of transactionId and appTransactionId values, even when initiating fresh purchases with unique appAccountToken values. Problem Summary: Purchase Stream Returns Old Purchases When calling buyNonConsumable() with a new product, the purchase stream still returns data for a previously purchased product, despite clearing all Sandbox transactions and using a new applicationUserName for each attempt. Transaction IDs Reused Across Distinct Purchases Even when generating a new UUID for appAccountToken on each purchase, the returned appTransactionId and transactionId are reused — this breaks our server-side logic, which expects these fields to uniquely identify purchases and users. Example Logs: // First purchase { "appAccountToken": "2d5a0880-f68e-44a7-a414-f51204e63904", "appTransactionId": "704464472748013865", "transactionId": "2000000928154716" } // Second purchase (different user context) { "appAccountToken": "2d5a0880-f68e-44a7-a414-f51204e63904", "appTransactionId": "704464472748013865", "transactionId": "2000000928429780" } Even when using a different productId, the appTransactionId stays the same. When using StoreKit1, the productId updates properly, but the transactionId still matches the previous one. This behavior also affects App Store Server Notifications (V2): we have observed notifications tied to appAccountTokens from completely different user accounts (based on internal logs), sometimes delayed by days or weeks. I’ve prepared a reproducible example using the official Flutter in_app_purchase sample with minimal changes — you can find it here: Github gist The code is almost identical to the package example. I only added UUID generation for applicationUserName in _getToken(). In the actual app (not in this example), I retrieve the token from an API. Additional Observations from the Community: We’ve also found similar issues reported in other frameworks and languages. For instance, a developer using react-native-iap observed that App Store Server Notifications in TestFlight were tied to previously deleted users, even after signing up with a new user account and generating a new appAccountToken. Details here: User A deleted → User B signs up → receives upgrade event with User A’s token Notification uses appAccountToken from old account, not the new one This strengthens the suspicion that the issue may be related to how Apple associates transactions with Apple IDs in test environments. Questions: Is it expected for transactionId or appTransactionId to persist across purchases within the same Apple ID, even for different user contexts (e.g., separate logins in the same app)? Is there any official recommendation for avoiding this kind of data reuse in Sandbox or TestFlight environments? Should I expect appAccountToken in server notifications to always match the latest value provided during the purchase? Thank you in advance for your assistance. I would appreciate any clarification or advice regarding this issue, as it impacts production logic that relies on these identifiers being unique and consistent.

StoreKit sandbox purchase and product fetch not working (IAPError: storekit_no_response)
💬 Post Content Hello everyone, I’m currently testing In-App Purchases (auto-renewable subscriptions) for my iOS app, and I’m experiencing an issue where the product information cannot be fetched from StoreKit. ❓ Questions For sandbox testing, is it absolutely necessary to submit a new app version for review (with the in-app purchase included)? Or can I test subscriptions without submitting a new build to App Review? Under what conditions does the error IAPError(code: storekit_no_response, source: app_store, message: StoreKit: Failed to get response from platform.) 🧪 What I’ve Tried • Confirmed that the bundle identifier matches the App Store Connect record • Verified that In-App Purchase capability is enabled in Xcode • Ensured the sandbox tester account is logged in (Settings → App Store) • Removed the StoreKit configuration file to use the sandbox environment • Tried both real device and simulator (same error) • Accepted the Paid Apps Agreement in App Store Connect • Products are created but currently not yet submitted for review 🔍 Environment • App type: iOS app built with Flutter (using in_app_purchase plugin) • Build type: Archive build installed via Xcode (Run on device) and testFlight • StoreKit Configuration File: Currently removed (for sandbox test); • Status: Ready to submit in App Store Connect

StoreKit 2 - Is it necessary to finish unverified transactions?
The sample code provided in https://developer.apple.com/wwdc21/10114 doesn't appear to call finish() on unverified transactions, and I haven't been able to find any documentation regarding what to do with unfinished transactions. However, Apple has always emphasized the importance of finishing transactions, and since a transaction object is provided even with the unverified state, I'd love some guidance!

User charged, but .userCancelled returned
Hello, Is anyone else seeing Purchase.PurchaseResult.UserCancelled, despite a successful transaction? I had a user notify me today that he: Attempted a purchase Entered payment credentials Was asked to opt in to email subscription notifications Opted In Was shown my app's "User Canceled Purchase" UI Attempted to repurchase Was alerted that he was "Already Subscribed" I have adjusted my code to check Transaction.currentEntitlements on receiving a .userCancelled result, to avoid this in the future. Is this logically sound? Here is my code - please let me know if you see any issues: func purchase(product: Product, userId: String) async throws -> StoreKit.Transaction { let purchaseUUID = UUID() let options: Set<Product.PurchaseOption> = [.appAccountToken(purchaseUUID)] let result = try await product.purchase(options: options) switch result { case .success(let verification): guard case .verified(let tx) = verification else { throw PurchaseError.verificationFailed // Show Error UI } return try await processVerified(tx) case .userCancelled: for await result in Transaction.currentEntitlements { if case .verified(let tx) = result, tx.productID == product.id, tx.revocationDate == nil { return try await processVerified(tx) } } throw PurchaseError.cancelled // Show User Cancelled UI case .pending: throw PurchaseError.pending // Show Pending UI @unknown default: throw PurchaseError.unknown // Show Error UI } } @MainActor func processVerified(_ transaction: StoreKit.Transaction) async throws -> StoreKit.Transaction { let id = String(transaction.id) if await transactionCache.contains(id) { await transaction.finish() return transaction // Show Success UI } let (ok, error) = await notifyServer(transaction) guard ok else { throw error ?? PurchaseError.serverFailure(nil) // Show Error UI } await transaction.finish() await transactionCache.insert(id) return transaction // Show Success UI } The only place the "User Cancelled Purchase" UI is displayed on my app is after the one instance of "throw PurchaseError.cancelled" above. This happened in Production, but I have also seen userCancelled happen unexpectedly in Sandbox. Thank you for your time and help.

AppStore response times for the store test environment to make purchases is very long.
I enter the payment wall, there it takes more or less 3 to 4 minutes to show the plans, when I select the monthly plan the loader is shown and from there the pop up to make the purchase in sandbox does not appear, I have waited until a maximum of 50 minutes and it is not shown, I go back and close the app I do the same steps and I am still there, without showing the pop up. Doing this same process in xcode, everything happens immediately without any interruption.

When is the unverified branch of AppTransaction.shared entered?
Hi all, I am adding the following StoreKit 2 code to my app, and I don't see anything in Apple's documentation that explains the unverified case. When is that case exercised? Is it when someone has tampered with the app receipt? Or is it for more mundane things like poor network connectivity? // Apple's docstring on `shared` states: // If your app fails to get an AppTransaction by accessing the shared property, see refresh(). // Source: https://developer.apple.com/documentation/storekit/apptransaction/shared var appTransaction: VerificationResult<AppTransaction>? do { appTransaction = try await AppTransaction.shared } catch { appTransaction = try? await AppTransaction.refresh() } guard let appTransaction = appTransaction else { AppLogger.error("Couldn't get the app store transaction") return false } switch appTransaction { case .unverified(appTransaction, verificationError): // For what reasons should I expect this branch to be entered in production? return await inspectAppTransaction(appTransaction, verifiedByApple: false) case .verified(let appTransaction): return await inspectAppTransaction(appTransaction, verifiedByApple: true) } Thank you, Lou

Unresolved pending purchases for consumables
In our app we are running into a few issues with pending purchases staying on receipt indefinitely. These are consumable purchases where we received the purchase succeeded from apple but then something went wrong on our servers to validate and confirm the purchase. At this point the purchase stays on the apple receipt indefinitely or until we confirm it. The problem is there are lots of scenarios where we can't confirm purchases anymore (like a game world expired/banned player/etc). So there's a few things I'd like to know to see how this could be handle correctly. 1- Was the user already charged, and if yes would they ever be refunded if the purchase is not confirmed (some sort of expiry)? 2- Is there a way to cancel this sort of pending transaction directly from the app or backend? 3- If one of these users asked for a refund from apple would this clear the purchase from the receipt? Any information would be greatI couldn't find a lot of info on this topic.

StoreKit2: appAccountToken in purchase() always returns first value instead of updated UUID
Hello, I’m experiencing an issue with StoreKit 2 when passing a new appAccountToken for each purchase request. Case-ID: 15948169 (for DTS reference) Description of the Problem When initiating a purchase, I generate a new UUID to use as the appAccountToken: let serverTransactionId = UUID() let options: Set<Product.PurchaseOption> = [ .appAccountToken(serverTransactionId) ] let result = try await product.purchase(options: options) Expected Behavior: Each new purchase should return the updated appAccountToken that I pass into the purchase options. Actual Behavior: The payload response after success always contains the same appAccountToken from the very first transaction. It ignores subsequent UUIDs I pass and keeps reusing the original one. This causes issues because the same identifier is being reused across multiple transactions, making it difficult to map purchases to the correct user session. Steps to Reproduce Generate a fresh UUID using UUID(). Pass it as .appAccountToken when calling purchase(). Complete the transaction in the sandbox environment. Inspect the payload response → The appAccountToken value is always the same as the first one used, not the newly provided one. Additional Info I do have a focused test project that reproduces this issue. The issue appears specific to appAccountToken persistence across multiple transactions. Has anyone else experienced this behavior with StoreKit 2? Is this expected (Apple caching the first token) or could this be a bug?

Storekit configuration broken in Xcode 16.4 the file has been changed
Hi everyone, After updating to Xcode 16.4, my StoreKit configuration stopped working. Whenever I run the app with a .storekit file set as the active scheme, I immediately get this alert: “The file has been changed. Do you want to save your changes or revert to the file on disk?” No matter if I choose Save Anyway or Revert, StoreKit testing does not work - the purchases are not simulated, and the scheme is basically broken. This issue didn’t exist in Xcode 15.4 - the same StoreKit configuration file works fine there. What I tried so far: Clearing Derived Data - no effect Making sure no scripts/tools modify the .storekit file - still happens Restarting Xcode and macOS - no change Environment: Xcode 16.4 Happens in both Simulator and on device Reproducible 100% Has anyone else seen this in 16.4? Any known workarounds until Apple fixes it? Thanks!

AppStoreServerNotificationV2 EXPIRED event after removing from sale
Our app is supposed to be removed from sale on May 31st. Subscriptions our app is offering will also be removed on May 1st one month before our app removal. I would like to know if AppStoreServerNotificationV2 EXPIRED event will be sent to a specified endpoint after the removal of these subscriptions. I think each subscription will be canceled automatically from May 1st to May 31st and it will send EXPIRED event to our server, but is it true? Thank you in advance.

AppTransaction.shared doesn’t return originalAppVersion for users who installed the app in 2017
Hi, I'm using the AppTransaction.shared API to retrieve the originalAppVersion, but I'm encountering issues for users who originally installed the app in 2017. Specifically, the property doesn't seem to return the expected value (or returns nil) for these older accounts. I have verified this issue using a real App Store purchase from 2017. Steps to Reproduce: Use a test account that originally downloaded the app in 2017. Call: let shared = try await AppTransaction.shared print(shared.originalAppVersion) Observe that originalAppVersion is missing or not returned correctly. Any insights on whether this is expected behavior for very old App Store purchases, or if there is a workaround to reliably detect the original app version? Thanks in advance!

Increased StoreKit errors “Unable to Complete Request”
Since January 28, 2026, we’ve noticed an increase in StoreKit-related errors during purchase flows. Specifically, we’re seeing a spike in errors reported as “Unable to Complete Request”, categorized as unknown StoreKit errors. This correlates with a noticeable drop in the overall purchase success rate. A few observations: The issue is not limited to the latest app version, it also affects older versions. It appears to occur only on iOS 17+. The impact seems country-specific: some regions are affected more heavily, while others show no significant change compared to previous days. At the moment, there are no related incidents reported on Apple’s System Status page. Given these symptoms, this looks like a potential StoreKit / Apple API issue, but we haven’t found any official confirmation yet. Has anyone else observed similar StoreKit behavior recently on iOS 17+? Any insights or known issues would be greatly appreciated.

Unknown Error when Trying to Add New Offer Codes
Hi there! Whenever I try to add a new Offer Code for my app's subscription, I get an unknown error. When I get to the last step of the "Create Offer for Codes" flow, I get an error that error reads "An error has occurred. Try again later." I have been getting this same error for over a week now, so any help figuring out how to add new offer codes would be greatly appreciated!

Double-counted consumable in StoreKit unfinished and updates workflow
In Getting started with In-App Purchase using StoreKit views and the corresponding sample project, Store simultaneously enumerates Transaction.unfinished and Transaction.updates. Since, "if your app has unfinished transactions, the updates listener receives them once, immediately after the app launches," it appears that Transaction.unfinished would also receive the same unfinished transactions causing handle(updatedTransaction:) to be called for twice for each transaction, causing consumables to be double-counted. Is this a bug in the sample? Is there more information on concurrent execution of unfinished and updates?

Promotional offer purchase fails in Sandbox with ASDServerErrorDomain 3902 after payment sheet
Hello, I’m integrating promotional offers for auto-renewable subscriptions using StoreKit 2. The offer is displayed correctly, the Apple purchase sheet appears, and I can start the payment flow. The sheet shows the correct discounted price and the end date of the offer. However, after confirming the purchase, an alert appears saying “Unable to Purchase - Contact the developer for more information” When dismissing the alert, Xcode logs the following: Purchase did not return a transaction: Error Domain=ASDServerErrorDomain Code=3902 "No se ha podido realizar la compra" UserInfo={ NSLocalizedFailureReason=No se ha podido realizar la compra, client-environment-type=Sandbox, AMSServerErrorCode=3902, storefront-country-code=ESP } Test environment: App installed from Xcode on a real iPhone Logged in with a Sandbox Apple ID Using StoreKit 2 Promotional offer applied using: Product.PurchaseOption.promotionalOffer(_:compactJWS:) On the server side, I generate the promotional offer signature exactly as described in Apple’s documentation: https://developer.apple.com/documentation/storekit/generating-a-signature-for-promotional-offers The signature is generated using a Subscription Key Signed with ECDSA + SHA256 Uses the correct invisible separator (U+2063) The signature is validated locally using the derived public key and verifies correctly The sandbox user has had previous subscriptions, which is why this promotional offer is eligible and shown. Given that: The offer is displayed correctly The purchase sheet shows the discounted price and duration The signature validates locally The error occurs only after confirming the purchase My question is: Is this a known limitation or issue with promotional offers in the Sandbox environment? Should promotional offers be tested exclusively via TestFlight instead of Sandbox? Any clarification would be greatly appreciated. Thank you!
