They added the ability to record a custom Siri command to trigger a workflow, perhaps that might help.

No, they also broke all forms of watch input. There is zero UI for shortcuts on the watch, so I can’t tap a complication and use a simple menu to fetch ETAs for public transit anymore.

You missed what the parent was saying - assign your shortcut a Siri phrase and then use it in your watch. I’ve been doing that since the Shortcuts beta started and it’s fine.

It doesn’t work when the background actions require some form of interaction
