It seems other people have had this issue before, but there’s no solution: clicking “logout” doesn’t always redirect to the login page. I’m saying it doesn’t always do that because it works okay for me in Brave, but not in Firefox so far. Can’t say any more at this point… 
Any ideas?
I would check Console in browser’s Dev Tools. From that other topic I understand redirect should happen from JavaScript. Sounds like a JS error to me.
