I had to wipe clean and restore my iPad Air 2 a month ago when the iOS 13 update bricked it (lots of threads on this). Now, after I've restored from an old backup, it's asking me every once in a while for the password associated with my daughter's Apple ID. We've never shared a device or an app or anything. This is weird. Any ideas? I've checked in many ways to make sure: the iPad knows that it's mine and not hers.
