It seems I am logged in after all, but still stuck in a loop. When I start a game, my username briefly pops up underneath the board, but then the game is cancelled immediately (see top of screen).
App: Logged out and cannot log in
Nice. I managed to log myself out on my phone, and to be able to login again I have to prove I'm a human. But there is no way to do that. No CAPTCHA, no nothing. I pay for a diamond membership guys, but I'm not paying to get locked out.
Great. On top of this I also cannot change my email address because verification mails don't seem to arrive, also not in spam. I pay $120 a year for a diamond membership. Small bugs are acceptable but this is messed up.

So I am not the only one with this - I just lost a game and could not do analysis, then it asked for verification I am human. I logged out and deleted reinstalled app.
It wouldn't even let me play a game as guest mode, but obviously its only the app on the phone, not the computer.

Same boat, what is going on?

Your in luck. We have a thread just for people like you.
Once you have completed the required exam, you can then log in.
We WILL need to see your high school transcripts, a fingerprint test, the last time you went to confession, your travel passport, driver license, street address, date of birth, results of The Rorschach inkblot test, last 3 tax returns, and a Presidential pardon.....which would come from Erik.

After the last app update I'm suddenly logged out on iOS. I was presented a CAPTCHA once, and after that I am stuck in some kind of loop, unable to get to a login form.
