I am trying to test purchases in TestFlight on watchOS.
Unfortunately, I get the following user-facing alert: “Account not in this store: Your account is not valid for use in the U.S. store. You must switch to the Czech store before purchasing.” Buttons: “Change store”, “Cancel”.
Tapping on “Change store” opens the App Store. An empty sheet slides in for a second, then disappears. That’s it. The issue is not resolved.
This all sounds very wrong, I am in the Czech store all this time. On a paired iPhone, everything works flawlessly.
