gift card purchase
I have a iphone4s ( with iOS 9.3) and my daughter has a iphone 4 ( with iOS 7) . She has to seek my permission before making a purchase on iTunes and this was straightforward in the past as I would simply respond to a notification sent to me as a result of her request and type in my Apple password..
Recently she was due to go to Spain and she wanted to make some iTunes purchases. I received the notification and typed in my password but no purchase was made .As time was limited I gave her a £20 Apple Gift Card. How does she make a purchase with the gift card and do I need to give her my authorisation ?
iPhone 4, iOS 7.1.2
