Unable to close/quit Compass App on Apple Watch Ultra

I had the same issue but figured out what the issue is. It is probably being caused by the back track feature having been activated (the feet icon on the bottom right hand corner of the compass). If this has been started, the watch is recording your steps to enable you to retrace them should you have to, which is why the compass app is kept open and active. To cancel this, press the steps icon and select ‘delete steps’. The compass app can then be closed as normal.

Make sure back steps app everything is un-clicked and not recording! Mine kept popping up too!

I am having the same issue, had to reset the watch to stop it coming up. After reset tried the app but same no buttons work

Thanks brisfrenchy! I'm on hold right now with Apple support, and she's stumped.

I woke up to the same issue this morning. Even sitting still at my desk the compass app pops up.
