Charge 2 stopped syncing all of a sudden

[Godsmaniac]

I own a charge 2 which stopped syncing all of a sudden so I logged out from the app and uninstalled it in order to check technical problems. But after reinstalling the app I’m unable to log in to my account even after the email and password are correct. Also I removed my charge 2 from my devices and cannot pair it again since them

Hello and welcome to the Fitbit Community @Godsmaniac 

I understand your having issues with both logging into your Fitbit App as well as Bluetooth issues. Let’s try these few steps to see if we can’t get you back up and running again. 
First let’s address the Bluetooth issue:

Lets try turning the Bluetooth off then on again 

if that doesn’t work let’s restart your Charge 2 (you will not lose data doing this) Please look here for the proper way to restart your tracker: https://help.fitbit.com/articles/en_US/Help_article/1186

Now let’s address your login issue. Please turn off your iOS device completely, wait 1-2 mins then restart your iOS device. Now try logging into your Fitbit App as you normally would with your email address and password. 

😃 Please let me know if these suggestions helped resolve your issue. Keep me posted
