iPad Air 4th generation will not update to iPadOS 16
As the title says, my iPad Air 4th generation will not update to iPadOS 16. I just updated to iPadOS 15.7, but when I go to Settings --> General --> Software Update, it says iPadOS 15.7 — iPadOS is up to date. Restarting the iPad doesn't solve anything.
Does anyone have the magic solution? Thanks in advance!
iPad Air, iOS 12
