Signing Up With Google No Longer Locks You Out
New accounts that linked Google and had not yet set a PIN could not reach any page at all. Two mandatory setup steps, accepting the Terms and setting a PIN, each sent you to the other one, and the browser eventually gave up with a too-many-redirects error. There was no way out of it from your side, because both steps run before anything renders.
The Terms page is now reachable while the PIN step is still outstanding, so the order is the one it was always meant to be: accept the Terms, then set your PIN, then play. Three accounts had been stuck at that door since signup and never had a usable session. They are through it now.
