How can I use my Apple ID balance for IAP?
I’ve just redeemed a gift card and in total it’s $30. I was going to use it for the 1 year videostar pro subscription which is $29.99. But when I try to purchase it I do my Touch ID and password then it brings me to AppStore asking for either debit card or PayPal and i want to use my Apple ID balance but when I choose the Apple ID balance payment method is just says add money or redeem. Can someone help me with this?
