UPDATE: I've viewed a WWDC22 video ("What's new in StoreKit testing") which says to create a second storekit configuration file syncing it with the in-app purchase defined in Apple Store Connect. The new read-only file is indeed syncing; but, it is STILL NOT WORKING.A print statement to the console, says that, in sandbox mode, requestProducts() in the Store manager is unable to find any products (though it works as expected when the scheme is reading either of the local store kit config files).

Addendum -- In the console I get this: Error enumerating all current transactions: Error Domain=ASDErrorDomain Code=509 "No active account" UserInfo={storefront-country-code=USA, client-environment-type=Sandbox, AMSServerErrorCode=0, NSLocalizedDescription=No active account}

You might be having the same problem I am having. Out of curiosity: where does the data that is working for you appear in CloudKit, i.e. Development / Production && || Private / Public? Mine should be going to Production - Public but gets recorded in Production - Private. So my Beta testers only see their own records when they should be seeing a composite of all.

Yes. Schema changes have already been pushed to production.
