The issue seems to be fixed.

Got a reply from them, they asked to submit a Feedback Report, which I did: FB13705173

I submitted a support request to Apple last Thursday (March 28th), but have not heard anything from them. Maybe it helps if others contact Apple, too. The issue is extremely annoying because app users don't understand and contact us to ask for the offer terms. Apple, please comment and help! :o/

Same problem here, any help from Apple, please?

Download Xcode 15.0 (15A240d), re-compile, re-submit. That will help.

Same here, I have to change the version info in the 'Build settings' >>> 'Versioning'.

Products are delivered through the Sandbox for me, but now it produces this error during purchase: https://developer.apple.com/forums/thread/726675

The issue seems to be fixed, products are delivered to the Sandbox again, at least for me.

I think I have the same issue, but thought it was related to the new 'Base price' functionality, which I had enabled for my In App products yesterday. Unfortunately I did not test if everything was fine in Sandbox before I enabled the new Base prices ... Anyway, I am using RevenueCat and RevenueCat now no longer delivers those products to my app, it says in debug mode that all In App product IDs are wrong, so I believe this is the same issue. Can someone from Apple comment or confirm, please? It looks like only the Sandbox is affected, as all products are still delivered in Production.

I See that happening from time to time, too. When I re-submit the same binary, it works. Must be a problem on Apple's end.

@aurelienporte I am having the same problem but did not find any way to fix it. Did you solve it somehow? Thanks!

The solution mentioned below works fine for me. Many thanks!

You tried the solution mentioned here: https://developer.apple.com/forums/thread/657913 ?

Yep, that makes sense now. Many thanks! :o)

What I have found is that the localization does indeed work, but it sporadically fails while debugging. Restarting my device fixes it sometimes, but not always. Maybe that helps.
