How do I delete an old account that is preventing me from logging into a new account? The login keeps reverting to the other Dropbox account that was set up long ago. I can’t override that. It appears I need to log out of that old one first, before I can log into the new one. It was set up by someone else years ago, prior to 2-step verification. That code is of course being sent to the Gmail account that someone else set up – which I can’t access to get the code! So, I can’t log in, which means I can’t log out of that one.
