Hello Quinn, thanks for your reply. The deployment target is iOS 17.7 In the Enhanced Security capability I also added Hardware Memory Tagging (but not the soft mode) The project had C++ code in it, since I did use the Receigen App (Mac App Store) for receipt validation, but I removed all the code including OpenSSL when I switched to StoreKit 2. Currently the project just uses Objective C / plain C and Swift but no C++. Cheers Brian

THX :)

I am a little bit confused: Since our users have(!) their app data in the app group container we should: not switch to a profile based app group or switch to a profile based app group (and omitting the Team ID prefix, since it is automatically added) ?
