airplay 2 and Denon AVR 3311

I have been using a Denon AVR3311 connected to my Mac mini for years. I have been enjoying my Music played by my DENON AVR 3311 through AirPlay.

Seems that, for some month, there has been an Airplay update and I get an error on my Mac saying: "This device is not compatible with this verison of iTunes".

It's very embarassing and desappointing. I've got state of the art computer and HiFi system and now I get this horrible error. Thanks for updating iTunes in order to stay compatible with former AirPlay OEM players.

Looking for feedback from Apple support.

Kind Regards.

Patrick.
