Apple Pencil does not work on iPad Air

There are a number of iPad Air models. We still need to know the exact one you have.

The 2nd generation Apple Pencil only works with either the 4th or 5th generation iPad Air. If yours is one of those, then what have you tried, so far yourself to resolve this, so that we don't offer potential solutions that may not have already worked for you?

Which exact model is your Apple Pencil? ... and what exact model is your iPad Air and is it still running iPadOS 16?
