I have the same problem. But I don't want to change the format and it's still recommended in the documentation.

IAPS that are consumable are shown as non-consumable in TestFlight when purchasing (can't purchase them multiple times)

No one at the Apple Store at the Genius Bar could help me either. Whenever I compile something with XCode, the sound starts cracking. Running 12.4 Monterey, M1 Pro 14-inch 2021.
