Many developers are experiencing the same problem in both Sandbox and TestFlight: https://developer.apple.com/forums/thread/779023

In TestFlight, I am experiencing the same problem. I reported it using the feedback app: FB17064331.

The subscription renewal speed in TestFlight is 1 day for all durations. https://developer.apple.com/help/app-store-connect/test-a-beta-version/subscription-renewal-rate-in-testflight We can request a refund instead of cancelling. The refund would be done in 10 min after requesting.

I encountered a similar error when using List(_:selection:rowContent:) and selecting a row after updating the data source. I used "onTapGesture" for selection to overcome this problem. List(dataSource) { item in HStack { Text(item.name) Spacer() } .contentShape(Rectangle()) .onTapGesture { selection = item } }
