Under "Display Preferences", "Airplay Display" is set permanently to OFF. How do I troubleshot that. Both devices are on the same wifi network. I can't seem to get that Airplay icon to display at all. My iMac is on OS Catalina. I can't seem to connect to any other apple device: namely — my Macbook Pro or IPad Air 2.
