A:Answer The 5th Genration iPad Air is not compatible with the Apple Pencil Pro.
I upgraded from the 5th Generation iPad Air (M1, 10.9") to the iPad Air M2 (11") and discovered that my old Apple Pencil 2nd Generation did not align with the magnetic charger, and the M2 did not even recognize the older Pencil. I even tried pairing manually through the Bluetooth settings. That is when I noticed that they are not listed as being compatible with each other. I would expect the same problem between the Apple Pencil Pro and the iPad Air 5th Generation (M1, 10.9").
