Try the command below in a terminal it should manually enable sidecar.

defaults write com.apple.sidecar.display AllowAllDevices -bool true; defaults write com.apple.sidecar.display hasShownPref -bool true; open /System/Library/PreferencePanes/Sidecar.prefPane

Ugh, that explains a lot. When i had Catalina and iPadOS installed, i couldnt get Sidecar to see the iPad at all. The iPad is on my wifes Apple ID. Really dont like this "feature" :(

Thanks this command activates Sidecar on my real MacBook Pro and I did not have it in system preference
