Apple Watch Series 3 keeps shutting off
Both of my kids have Apple Watch series 3 watches. My older son has had his watch for over a year and it’s always worked fine. It started randomly shutting off about a month ago. My other son just got his watch today and it’s starting to do the same thing. Randomly shuts off with full battery. I have shut off both watch and device like many forums suggest. We’ve also unpaired and set up like a new watch again. Seems like a software update needed to fix the glitch as I have a series 4 and it’s fine and it just started. Any ideas on how to fix it?
