exceed maximum allowed authtokens?

I've been unable to use the android application for zoho. When I try to connect, it raises the error "exceed maximum allowed authtokens"

I've tried this solution: https://help.zoho.com/portal/en/community/topic/error-exceeded-maximun-allowed-authtokens but it didn't worked for me. I close all other sessions but it's still unable to connect, even though there are only two sessions opened.

Some ideas? I don't know what to do :(
