It does not work on the 5th generation Ipad Air. Only from the Ipad 6 generation, I was able to test it.

I have to correct myself, I don't own an Ipad Air so I can't say. My answer only refers to the Ipad, which is only compatible from the 6th generation onwards.

I use it with the iPad mini 6, and it works perfectly. Unfortunately I can't answer your question about the iPad Air (5).
