Question: iphone 6s keeps asking for a password associated with an old email address
I had to reset my iPhone 6s+ and restore everything from my cloud backup today. Now I keep getting interrupted by a pop-up message asking me to sign into the iTunes store using an old email address from years ago when our family used to share our iTunes library and a password I don't know. How can I determine what app/song/whatever is causing this so I can delete it or change the email address?
iPhone 6s Plus, iOS 11.2
