My app has a Siri Shortcut that works fine when I execute it from the Shortcuts app on my watch, but if I try to activate it by voice, Siri says: "Sorry, something's wrong. Please try again." and then a second later says "We've had a problem. Please try again."
I'm currently on watchOS 8 beta 6. I last tested this in early July with beta 2 or beta 3 and it was working at that time. I haven't made any changes to the intent extension since then.
The shortcut activates fine by voice on my phone, running iOS 15 beta 6. I'm also able to execute other Shortcuts by voice on my watch.
Has anyone else run into this before? Is there a way to debug the intent extension on the watch, so I can see if any of my intent handler code is even being called?
