I’ve been also struggling to make it work.
You really have to unpair and re-pair every time, but that wouldn’t be too much of an issue, if only it would work. The real issue is that it doesn’t work even when paired/connected. It doesn’t work as controller, you can press the buttons but nothing happens. it’s definitely an issue in the tv os, as the controller works with other systems. it seems that it’s a bug that needs fixing.
