my ipad showing an update for iOS 16.1

If you are currently enrolled in a beta programme and wish to return to using the current production version, this support page provides the necessary information to remove the beta from your iPad:

How to uninstall iOS beta software - Apple Support

iPadOS 15.7 is the most current production release.

I’m not sure, but I do know that discussions of the beta versions are not appropriate here.

DOn’t you guys have a beta forum to ask these things?

If so your question may be better asked there.

The beta can not be discussed here.
