The night this season of the Game of Thrones started, I kicked up HBO Go on my Apple TV and I had to re-authenticate. I get HBO through DirecTV Now.
I went through the usual steps and I came to a point where I had to sign in to my DirecTV Now account. I use 1Password to create long, complicated passwords. Usually in such situations, I use my iPhone and copy the password from the 1Password app to the Apple TV Remote app. For some reason, the app never removed the keyboard on the screen, so I had to use the Apple TV text input system just as if I was using the physical Apple TV remote.
I had to do this on two Apple TV shows six weeks ago, and then I had to do it again in ten days ago, again on both Apple TVs.
Has anyone else come into this? I checked my single sign of settings as best I could, but everything looks right. And the Remote App will give me a keyboard on the iPhone.
