Sense won't power on or sync
My Fitbit sense won't power on. It's been on the charger all night. I've tried all troubleshooting tips and nothing! Holding button for 10 seconds or more,cleaning connection with alcohol wipes,left on charger,tried a different charger and used laptop to charge. Restarted my phone. I uninstalled my Fitbit app,,turned Bluetooth on and off. Any other suggestions? When I go to the app, it won't sync to my s21 ultra phone. Can I take apart this watch? I've had it over 1 year, so probably no warranty.
