I phone 11 pro max iOS 16 is not accepting my correct passcode
Yesterday I unpaired my Apple watch from my phone and since then my phone has stopped taking my passcode. I have made a few attempts and it's showing me "iPhone unavailable try again in 3 hr and later 8 hrs. I know that resetting my phone and erasing all data is the solution why should customers suffer because of this bug due to the latest iOS? Kindly help in resolving this issue so I don't lose my data.
iPhone 11 Pro Max, iOS 16
