I want to gift an app from the iOS app store. I verified I have enough prepaid store credit, set up the gift purchase, and clicked the Buy button.
The iOS App Store gives a false error message:
Payment Information Required
A method of payment is required to buy an iTunes Gift. You can add a payment method from your Account Information Page.
I checked my account information and it has enough prepaid store credit to buy the app as a gift.
What's causing this and how do I fix it?
