How iCloud storage is billed.
My wife and I share a Family Plan with me as the organizer. We both have expanded our iCloud storage to 20gb. The problem I'm looking to solve is that my extra storage is billed to our iTunes Store credit but her's is being billed to the credit card associated with the account. How do you get BOTH storages to bill to the iTunes account? We both have individual iCloud accounts but share the billing account (mine) under the App Store and iTunes Store.
