The airplay doesn't turn "on"
Hello Happy new year to everybody! I have a Mac book air (Middle 2019) and an iPad (5th generation) I tried to choose sidecar but I discovered that the option at airplay monitor is always "off" and I can't turn it on (there is no option) My firewall settings are ok , so as iCloud... I appreciate if somebody has an answer
Thank you
MacBook Air 13", macOS 10.15
