Was able to successfully add a family member to my share plan. I am listed as the organizer with a valid credit card listed. The family member can see all my iPad apps on their end. Paid apps show up as FREE. However, the second that family member tries to download the app, an error message appears that says "Shared content isn't available. To access shared content, your Family organizer must update your Family's payment method." Have no idea what needs to be updated. Payment info. is listed on my organizer account. PERHAPS the reason is because I authorized share on my iPhone 6 Plus and the family member is using an iPad. Also... I take it anything I downloaded PRIOR to the family sharing should be available as a share?
