My wife’s Fitbit Charge 5 which she’s had for a year, stopped working. We had to reboot it yesterday and it seemed to be working fine but today after a swim it stopped working and only pops up the Fitbit symbol when I reboot it. She’s had no issues swimming with it before. Not sure if the battery is gone or water got in or what. Looked but can’t see how to do a hard reset on it outside of the screen.
