It doesn't support the new remote control, too bad (even if I don't have it), but Share Play is a real shame for watching a show with several people.
Then for the bugs, there are quite a few and I haven't been able to change channels with Siri on Apple TV for a while now and yet it worked very well before, and it's all the more harmful with a remote control without key 1-2-3…
Then Spacial audio is not supported if I'm not mistaken?
It's a shame this application was very good at the beginning and in advance but today I have the impression that it is the opposite.
