How do I change my billing address phone number without deleting my payment method?
Reviewing my Apple ID on my computer it shows an old phone number (that I wish to change) under the billing address of one of my cards and it says you can change it from your phone or iTunes. I went to the Wallet & Apple Pay section on my phone and it does allow me to change my billing address for that card but it doesn't show the old phone number that is visible on the Apple ID Manage your account section on my computer, so how do I change it without deleting my card? because that would end my subscriptions.
iPhone 6s Plus, iOS 13
