So here's something interesting that I haven't seen documented anywhere. Since the Apple TV is now an AirPlay 2 device with the latest update, you can use Siri on any of your other devices to control it, both audio AND video. For example, I can now tell my HomePod, "Pause the Living Room Apple TV", and it pauses the movie I'm watching in Netflix in the living room. I activate Siri on my iPhone and say, "Skip back 10 seconds on the Bedroom Apple TV", and it skips back in the show that I'm watching in Plex in the bedroom.
