I have a centurion Amex card, why have I received an email today that my card is no longer connected with apple pay?

Did you call Am/Ex and confirm the email was from them? As I’m sure you know, you have a private number to call. Do not respond to the email. Please use a confirmed phone number to Am/Ex.

Apple doesn’t offer email support. In the US, you’re welcome to call 1-800-MY-APPLE. You can also chat with Apple Support using this link.
