It has been staying an hour ahead and I have tried everything to correct it uninstalling the app and reinstalling it and it has been way off on the sleep it only seems to record parts of my sleep pattern and on the period schedule it changes every single month of I start early I change it in the app and it still gets off schedule, please fix these issues because I love my fitbit and I am gonna I guess just have to try a different brand watch one that doesn't unbluetooth so often. Thanks
