Update 6/11/2018: Hello! This issue has been resolved in app version 2.52. Please update your app if you haven't already. Thanks for your patience and flexibility with using the workaround.

Update 5/30/2018: Hi Everyone - thanks for your patience as we work on a fix. We believe this may have to do with account settings. If you are still unable to log in, I have a workaround that you might want to try:

- Open your device's settings menu.

- Tap on 'General', 'About', and then 'Name'.

- Remove any special characters or symbols.

- Save your settings.

- Attempt to login to the Fitbit app again.

I'll continue to update this thread as we work toward a fix. Thanks again for your reports.

Update 5/26/2018: Thanks again for your reports as we continue to work on this issue. If you continue to experience this, if available, please trying logging on with another device or on Fitbit.com. Thanks for your patience as we work on a fix.

Updated 5/24/2018: Hi Everyone - I've merged a few threads together. We are aware that some users are being logged out of their account and when trying to log back in, and receive a notification 'this account is pending deletion' when this request was not made.

Please note: Though @MarcoGFitbit had some good tips that worked initially, at this time we do not recommend uninstalling and reinstalling the app, this will not fix the issue . Also, resetting your password and updating the app will not resolve the issue.

I'll update this thread as I hear more, thanks very much for your reports!
