Running into the same issue here as well. Tested with both a MacBook Pro M1 chip as well as a MacBook Air w/ M1 chip. Both devices show the Airplay device, click to connect, enter the code, aspect ratio changes on the Mac, and you see a black screen on the TV. It shows it is connected via AirPlay, but nothing is ever shown on the TV. The TV is a Sony - 85" Class X800H Series LED 4K UHD Smart Android TV. Model number XBR85X800H.
