BigSur doesn't show iPad for SideCar
I've installed BigSur yesterday.
First thing I've noticed, I can't use my iPad Pro as a SideCar any more. I've went through all the check lists (iCloud account, Bluetooth, Wi-Fi...) with no bliss.
When I go to the Control Centre > Screen Mirroring, oddly enough, I can see my Apple TV, but not my iPad.
My iPad is connected to the iMac through a cable.
Any tips?
iMac Pro, macOS 11.0
