"Unable to Redeem" when downloading approved 1.0 app via promo code

My brand new 1.0 app is approved and pending developer release.

As part of my release checks, I like to download the app store release using a promo code. On both iOS and macOS, redeeming a promo code for the respective builds gives the error you see in the screenshot:

Unable to Redeem.

This content is incompatible with the current software on this device. Update your device to the latest software version and try again.

The app targets iOS 26.0, and my devices are running iOS 26.3, and it was built with Xcode 26.3.

I'm relying on this feature for sending a build to pre-release media for reviews/articles, and am worried I'll embarrass myself.

Other developers: Have you also had this issue? Do you know a work around for this issue?

Apple: Please help! Is there anything I can do?

I have a second app which is already live on the App Store. I pushed an update to this app, and it was approved and is Pending Developer Release.

I generated a promo code, and redeemed it. It worked fine.

So, maybe the Pending Developer Release -> Promo Code method for giving media access to your prerelease 1.0 builds no longer works.

Apple: Please document this!
