Siri vocal commands just stop working on our iWatch app after iOS15 watchOS8 upgrade. Triggering manually the shortcut works on both iPhone and Watch. Vocal command work on iPhone. I tried reinstalling, re-paring the watch, reinstalling commands app, reinstalling watch app. No way. When "Hey Siri, execute My Command" I always got the answer: "There is a problem, please retry" (on the watch). This started only after watchOS8 upgrade. Other Siri vocal commands with other apps work correctly. Any way to debug this?
