A week and a half ago, my Fitbit Charge 4 starting sporadically not tracking sleep stages. For the past 5 days, I have gotten basic information. I have tried all of the troubleshooting suggestions (fully charged, cleaned sensors, rebooted device, reinstalled app, restarted phone, etc.), and none of the work. At one point, I even switched the device out with my old Charge 2, but the issue remained. Has anyone else experienced this, and if so, how did you fix it?
