same here

besides, what a clumsy ui : trying to log out from a bunch of devices listed, as old as 3 years, and can't log out from all them in 1 go one has to logout from each single one, a list > 100 entries !, and tho deleting a few, they not log out, remain listed

I have the same issue and they won't close they're all still there after supposedly signing out.

Are you talking about sync?

Signing out is not removing. I don't see a way to remove something. I called for more help.
