It seems to be stuck in a "sign-in/verify" loop. It shows up in my trusted devices. I log in with Apple ID and password. I get the verification code and click submit and it loops back to Apple ID input screen. Then repeats over and over. I've tried rebooting and get the same issue. Any ideas?

I've tried that article as well and it didn't help. It did finally decide to work though. I'm not sure what changed. I had to sign in on the Apple TV (again) and at some point it forced me to re-enter my password on my iPhone. Then, again on the Apple TV.
Still not sure why it was such a pain, but it's working. Thanks!
