My watch is stuck in pool swim mode. I can't exit it. I can't power off. As the button to select does nothing. It does press normally but nothing happens.
Was working perfectly last night.
Update: this afternoon the watch dropped out of the pool swim activity and was left with a green triangle on screen.
I followed the instructions to reset from there. Nothing seemed to happen for a few minutes and then it came back to the watch face.
However the top right button does nothing now, so I can't get into an activity or accept any change.
