I was attempting to sign a build and upload to the iTunes store, but suddenly found all of my accounts had expired sessions. I tried to re-authenticate, but the activity spinner just came up and then disappeared not showing any sort of error message. You can see what happens in this clip: https://1drv.ms/v/s!AjVO8UHeoheeiQj_ahJDQpGqBVgH
I then deleted all my accounts to try to start over, and now I cant get in with any of my accounts.
My current theory is that it's due to the fact that I'm in a different part of the country than usual. I'm visiting friends in Florida, but I"m from Colorado. I'm just thinking maybe it's because I have two-factor authentication enabled? Does two-factor have any location component? Again, that's the only theory I have at this point. I am able to sign in to appleid.apple.com without any issues. It's just Xcode that won't let me in.
Any ideas?
