Lately I've noticed my watch not keeping proper time (corrects when connected to bluetooth), not tracking sleep, randomly turning off during the day and now there's a rattle when I move my wrist. It's not the straps, as I've removed them to check. I've briefly chatted with Garmin and they said connect to Garmin Express (which did nothing). Everything is updated and I even installed the newest beta version. Anyone having any of these issues?
