Sandbox errorCode 4040004 "App not found" — one app works, identical app doesn't

I have 2 iOS app products. One can fetch subscription product information normally, while the other fails with the error errorCode 4040004 'App not found' in Sandbox. The App Store Connect backend configuration should be fine, and the subscription code on the app side is the same codebase for both. I really can't find the root cause anymore — if anyone knows what's going on, please point me in the right direction.

Also, I'm able to sync/download the StoreKit product configuration file from App Store Connect directly in Xcode, which should also confirm that my App Store Connect backend configuration is correct.

same problem for me

I also encountered the same problem

Same problem. For me, the consumable products can't be purchased, even though the metadata such as price are loaded correctly.

Same here, has been stuck here for 2 business days and checked every config a hundred times, wtf is going on?

Apple's technical support team provided no clear answers either. After I emailed them, they simply advised me to review my configuration or post my inquiry on the user forum.
