Updating Apple ID settings
My iPad pass code works for all things on my iPad except when I have to update my Apple ID settings. Any ideas?
iPad Air 3, iPadOS 16
Are “Screen Time / Parental Controls” possibly enabled?
They can be set to disallow changes to an AppleID or password from a device w/o first correctly entering the screen time password.
See more detail here in “… other Settings and Features”
