2.session.6

I got the error 2.session.6 and I had already logged in but when I wanted to re-enter the game I was just logged out and had to start and that's when suddenly I got that error and tried to reinstall it but still happens unlink my google account with skullgirls mobile and still happens, the truth...

Suddenly the game asked for my log in details again, so I pressed the google account button and now it doesn't let me log in, it says error 2.session.6, tried reinstalling and automatically log in to compatible games on google games settings, but no luck, didn't link my account to other games...
