LOL. Yes, they did. Typically we get a brief window of maybe a week to submit builds for review, but apparently not this year.

When I posted my original question, I thought I was stumped on finding a solution. Of course, only after posting my question did I have a hunch that this was due to the introduction of MPNowPlayingSession. It turns out that's the issue. On tvOS 14 -- at least in the current beta -- it seems that using the MPRemoteCommandCenter sharedCommandCenter doesn't work. Instead, you must: initialize a MPNowPlayingSession, passing in your AVPlayer instance make the session active via becomeActiveIfPossibleWithCompletion use the remoteCommandCenter property of the session, instead of MPRemoteCommandCenter sharedCommandCenter And of course, once you have created a MPNowPlayingSession, you need to use that session nowPlayingInfoCenter property to publish now playing info instead of MPNowPlayingInfoCenter defaultCenter. I will file a bug report about this, as I believe MPRemoteCommandCenter sharedCommandCenter should continue to work on tvOS 14, and the docs do not indicate that it is deprecated.

I'm wondering if this has something to do with the introduction of MPNowPlayingSession on tvOS 14, given that a MPNowPlayingSession also introduces a remoteCommandCenter tied to the session. I am not yet using MPNowPlayingSession (still using MPNowPlayingInfoCenter).
