Just a warning for people considering this first tvOS 12 public beta. I found the Computers app (for playing from a remote iTunes library using Home Sharing) to be basically unusable. Wrong artwork displayed if you shuffle, songs stop and kick back out to computer selection menu after 10 seconds etc. If you care about that you may want to wait a release or two. I hooked up an old AppleTV 4 with the release software to play my music/videos for now.
