Same here with Fitbit Charge 2 and Samsung S8. Since last night (South Africa / GMT+2) I have not been able to sync. Now I'm logged out completely and the app is completely unfunctional. Even the reset password button just spins and spins.

After restarting my phone, and waiting a REALLY long time on the login screen I'm finally back in the app and syncing

I have the Charge 2 and an old Samsung Galaxy 3.  I restarted the phone and got logged back on to fitbit, but having synch errors.

OK, I also did the update thing on the Charge 2.  Now it is syncing!
