Syncing/logging in failure

[Loaty]

For several months I have had problems being unable to sync my charge HR, it would never complete the sync.

I decided to uninstall the app and reinstall which required me to log in again. It refuses to log in, instead giving me this error message:

Failed to log in.your phone's time doesn't look quite right.

Then it proceeds to tell me how to set my phone automatically.

The issue here is that I am in Cairo, Egypt and Egypt did not follow daylight saving time this year. Despite that I still tried to set my phone automatically with an hour difference and still received the same error message.
I contacted Fitbit support on Twitter and the initial advice was to update the Charge with the latest firmware - which I obviously can't do without logging in! I pointed this out and they referred me to here.
Now I have lost all my training history after uninstalling the app and have a redundant tracker that cannot even function as a watch!

Help please!

Hi there @Loaty, welcome aboard to our Community. Indeed, if your are not able to log in to your phone's Fitbit app, it wont be possible to review if there are updates available.

When this issue occurred most of the times is due to the timezone is set in manual on your phone settings and should be corrected as soon you changed it to automatic. 

By any chance is possible for you to try with a Computer? If it does, I would recommend to pair your tracker again as a new device. For this might be require to install Fitbit Connect. Once you have the software, follow the first part of this other instructions.

If you don't have a computer available to try, then please  approach to our Customer Support Team for additional help.

Keep me posted how it goes, I'll be around.
