Hello Bigdessert,
Thank you for reaching out to Apple Support Communities, and we'll be happy to help in any way we can. We understand you're having issues with running a shortcut on your watch. First, try restarting your watch and the companion iPhone to see if that resolves the issue:
Restart your iPhone
Restart your Apple Watch
Then, try to run the shortcut again as described here: Run shortcuts from Apple Watch
"You can run a shortcut in the Shortcuts app on your Apple Watch or from a complication.
On Apple Watch, do one of the following:
- From the Shortcuts app, tap a shortcut.
- To run a shortcut as a complication, tap the complication on your watch face.
For more information on which shortcuts work well on your watch, see About actions in complicated shortcuts."
We hope this helps.
Cheers!
