Unable to update card details on App Store when my old card expires
I can’t update my card details and my older card is expired. Since I don’t have access to my other device that is the family organiser nor its credentials, it’s 10.000 miles away I wanted to buy a apple gift card and I can’t redeem it here since my account is registered in another country and I can’t buy one there because there they don’t have gift cards. Do I have to buy yet another phone and set up a new account?
