Can’t log out of my account

So I’m trying to co-write a story with someone but I’m having a issue logging out of my personal account without clearing my history to do it.

I can’t click on any of these buttons (account settings, notifications or logout)
they do nothing at all

You could try restarting it, or sometimes when you log in there’s a checkbox already clicked that says ‘keep me logged in for 30 days’, this might be the problem and you have to wait 30 days after you logged in before you can log in on a different account
