I have credit on my iTunes account, but buying things on mobile own't use that credit. How can I make it so buying a song or an app uses credit and doesn't charge my card?
A while back, I got a gift card for iTunes. I put it on my account so now I have a running credit of like $50. Yesterday, I bought a song but it charged my credit card instead. If I buy it on my desktop, this isn't an issue it seems (because there is a banner that says "Remaining credit: $XX.XX") but on mobile, it refuses to use my credit. Does anyone else have this problem?
