Ok. I have out it working. It maybe a combination of things, but possibly a reboot of the Apple TV was all needed.
Story: When I was setting up the presence for HK, I never turned on the Apple TV. When I couldn’t get the toggle to work while connected on 4G, I troubleshoot it and turn on Apple TV.
First thing it ask was authentication. Did that. Tested. Not working.
There was an update firmware. I was one update behind. Did that and not it works. Although, a reboot of the unit would probably had fix it.
