Samsung 7 series won’t airplay

It appears as though your TV is an Apple AirPlay-2 enabled device according to this.

Apple TV app - Devices - Apple

I have no problem using AirPlay on my Samsung Series 4. What happens when you try to mirror or AirPlay? Maybe this will help.

FYI, the Apple TV+ app that you reference is not the same thing as AirPlay. It is an App like Netflix, Prime or YouTube that is downloaded and accessible on the TV.

Nor should it.

Airplay is an Apple technology available on iOS devices only.

There is an app in the Google store that uses the term Airplay, but it does not appear to be compatible with Apple's Airplay protocol.
