Cant use IPad Air 4 as a external display to my 2017 Mac book Air
I have a 2017 Mac book air 13 inch running Mac OS Big Sur. I just bought a new IPad Air 4. I’m trying to use it as a external monitor to my Mac book but I can’t find the device on my Mac and sidecar it. I can find my Apple TV but my iPad isn’t popping up. Both are running latest Update, both connected to same wifi and both are connected to same Apple ID. This is strange. Any fix? Thanks.
