MacBook Pro 2015 Big Sur and AirPlay to Apple TV 4th Gen
Since the update to Big Sur on my MacBook Pro 2015, I cannot airplay to my Apple TV 4th gen. Apple TV is showing in the new notifications area but after selecting it, nothing happens. I just get a pop up few moments later saying couldn't connect.
iPhone 11 Pro can AirPlay no problem.
All devices are up to date, bluetooth is on etc.
If I go to Settings > Displays. Then select AirPlay Display and select my Apple TV, it just reverts back to off.
Show mirroring options is ticked but nothing is appearing in notifications bar at top. It did prior to the OS update.
MacBook Pro 13″, macOS 11.0
