Deleted Apple ID Account Keeps Asking for Password
An old deleted Apple ID keeps asking for password verification on a brand new iPhone 7 w/iOS 10.2 after apps have been installed. This old account is not longer on any of my devices nor does it show up in my Apple ID Accont on the Apple website.
How do I stop this Apple ID Verification box from popping up?
Thanks
