I have just had An update on my apple iPad Air, I would like to uninstall it beause its dreadful how can i do this please

It is not possible to restore an earlier version of iOS/iPadOS. If you have updated to iPadOS 15.1, you cannot return to iPadOS14.x.

You cannot uninstall an update. It’s for keeps. What version is it and what problems are you having?

It’s good to know that your problem has been resolved. Enjoy your iPad.
