Hi Ioannis,
Thanks for your email. I'm not sure I understand exactly the flow you're experiencing. Could you send a link to your website (either over the list or just to me)? A series of screenshots could work too
Thanks,
Jack

Thanks for sending the link. From what I can tell everything is working normally with account chooser. If the user's account chooser is empty it is redirecting to your login page, otherwise the account chooser is shown to avoid the user needing to type their email address manually. Remember this central account chooser is the difference between v1 and v2 ( https://groups.google.com/d/topic/google-identity-toolkit/NSy-VvcybtI/discussion )
There is a slight issue in that your sign up endpoint was not responding as expected, but otherwise everything looks fine
Hope that helps,
Jack
