Hey parkr, this just happened to me. I tried to use my github account to create a new account and that didn’t work. I also just tried logging in with it (on the off-chance it would work) and I still got the “error authorizing” message others got.
I finally just had to create a new account and that worked, but when I went to validate my account from the email, the authorization error message popped up again and that was nothing to do with clicking on anything with Github.
One last problem, when you finally do login, the new messages tutorial grey out doesn’t go away easily and I had to archive the hello message and click around for a while before it would finally stop greyying out everything saying I had a new message.
Hope this helps,
