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?
