I may have found a solution that might help others.
I was able to connect my Zwift Hub One to my Apple TV 4k, but somehow, Apple TV didn’t pick up the bluetooth signal from the Zwift Click. I knew the Zwift Click was working, because my phone and the Zwift Companion app were able to pick up the BT signal from the click.
The solution: I had my Zwift Hub One connected as a ‘Power Source’ on Apple TV. But as soon as I connected the Zwift Hub One as ‘Resistance’ as well, the Zwift Click appeared under ‘Controls’.
I hope this might help other people struggling with the same problem.
