This issue started while I was on a bike ride yesterday. About an hour into the ride, my watch buzzed a couple times in succession and I noticed that the timer stopped. I pressed the start/stop button and nothing happened. After a couple tries, it started again, and I finished my ride. Today, I was out on a run and again, about an hour in, the same thing started happening. Only this time, the button wouldn't work. About five minutes later after I had given up trying to press the button, the watch vibrated again and started timing. About five minutes after that, the same thing happened again, but now the start/stop button doesn't work at all.
Is there anything I can try to get the button working again? If not, is there a way to remap the button to some other function that's less useful (e.g. lap)?
Has any one else had an issue like this? Any help would be appreciated.
