Cannot Mirror Screens to Apple TV after update to Big Sur
I have updated both the Apple TV and Mac with all updates still can not mirror my screens. I have checked all settings and even went an upgraded to a newer Apple TV generation 5 from a generation 3 still no luck. It was working fine before the upgrade. Other devices can mirror just fine not the Mac Pro with the new OS on it. The message it says is it cannot connect. Any ideas?
MacBook Pro 15″, macOS 10.14
