Hi @NinPin
Moved this thread from the Charge to the Android section since being a app related issue & increases the chance of getting a solution.
- Make sure to be logged in to the same fitbit account on your phone;
- Ensure that the latest Fitbit App version is installed from the Google Play Store;
Feel free to log out from the Fitbit App & login again..
If having installed a previous Fitbit App update over a existing version, it may be worth a try to uninstall the installed version first, then installing the fitbit app freshly, as sometimes glitches can occur when keeping installing newer app versions over installed apps..
