Update Credit Card details
How on earth are you supposed to update your credit card details on an iPhone? If you click "edit" the only option available is to "Remove" which it wont allow you to do as it is attached to an account. So if I try and add an additional method of payment which is the new credit card details, it says these details are already registered even though they have different expiry dates and CVV numbers. I just go round in big pointless circles.
