Applewatch work-out can't be stopped anymore
Have been very happy and enthusiastic with my Applewatch so far. Using it rather intensively for measuring workouts, primarily Elliptical and Outdoor walk. Lately it systematically doesn't want to accept the Stop anymore and just keeps running measuring. On the stop/pause/lock screen it seems to accept the push on Stop but then returns to the timer screen and continiuing the timing. Even stopping the watch and restarting doesn't stop the timer anymore and it's worsening....
It's an Applewatch 36mm with latest watchOS version.
Don't know what to do anymore, help, help!
