Peacock Network not playing on Apple TV.

We have the 4K Apple TV & I have a 6th generation iPad. I had ZERO problems with Screen Mirroring with all other streaming apps (HBO, YouTube, Prime, etc.) until Peacock. The AUDIO streams, but the video does not. (Meaning I see the video on my iPad but hear the audio on the TV.) The same happens with AirPlay.

Meanwhile, I’d loaded Peacock onto the Apple TV & logged in. I can find shows using the Apple remote, but NOTHING makes them play.

l’ve been trying to watch the first season of Superstore.

Is there a problem with Peacock or with Apple TV — or did I make a bad first choice of Superstore?
