My UR22C is not supported by Ipad 8 and Ipad Air 2?

I bought the great UR22C and i’m very disappointed : my Ipad 8 and my Ipad Air 2 dont recognize UR22C. An idea ?
Thank you very mutch.

We have to wait for the development of a firmware so that the UR22C is compatible with IOS14. It could be long, very long. Can the Steinberg team do anything ?
I am very disappointed.

It is seen fine on my iPad7!
