I have the same situation. It occurs in both 4k Apple TV generations, and it’s reproducible 100% with success every time…
This only happens when using the Old player. When shifting for the new player, the live tv channels play. This may be the reason @Spunky17 had success when uninstalling and installing again, because the new player is the default one.
My problem is that using the new player is not an option because of the really old problem reported in Here….
This is very disappointing, I really don’t understand what devs are doing in Apple TV development, really. What a mess.
