gnome-control-center online-accounts

Good job with bug report. Except you should explain what happened when you had login issue. I would edit it and remove the windows portion of it. IE.. Log in Failure : [Explain what happened, did it login or not. What steps you took.]
Click on the yellow circle to the right of the bug description to edit the bug report. Include any additional information
like you tried to login several times, etc.
