Just an observation.
In the last few days of January 2023 all of our ATVs running 16.2 started prompting [SharePlay "TV" content?] when starting a program using a streaming app. The choices were SharePlay, Start Only for Me, or Cancel. In addition the SharePlay icon on the ATV home screen uppeared in the upper-right hand corner.
Had to update to 16.3 to make the prompt and SharePlay icon go away.
