My actual fitbit seems to be working fine. However, my app for Android (Samsung Galaxy S7) doesn't work at all. My last sync was at 3:15 pm yesterday (April 28). I have restarted my fitbit 4 times, uninstalled my app and reinstalled it, hard restarted my phone, and turned Bluetooth on and off. It doesn't show any updates. I'm just puzzled because I have only had it since February. Is anyone else having this problem?
