Airplay2

I have an Apple TV 4K gen3 (A2843) and an iPhone 14 Pro.

I would love to be able to stream audio through Airplay to the Apple TV from the iPhone without it being interrupted by e.g. an incoming call. This doesn’t work at this point, so (at least) one of both is not supporting Airplay2 as the latter would (should?) make this work.

Does anyone know what device is causing the issue here? Both? Will Apple enable Airplay2 with an update on these devices?
