How to Update iOS 16 RC to Public Release?

I'm running on RC iOS 16.0 (20A362) and I would like to switch to public iOS 16 which was released just now.

I have already deleted beta profile in Settings, rebooted the phone but no new update can be detected.

It looks like I'm stuck on RC version.

Question is should I be able to update from RC to public release or this RC (released a week ago) is in fact same as Public one?

Thanks in advance.
