My credity card was replaced. When I go to my Apple account, and click on my credit card, there doesn't seem to be a way to replace the numbers. When I click on my card, it's all gray. Nothing changes.
How do I change an old credit card? Mine was discontinued, and when I go to Accounts and try to change it, it won't let me eliminate the card or add any new information.
iPhone 7, iOS 13
