how do i update my debit card renewal date used for monthly auto pay for i cloud

I have had this issue multiple times, unfortunately, I believe the only solution is to delete the 'old' card and add the 'new' card. Yes, I know it feels like it should be the same since the number didn't change.

This is an annoying safety feature about debit/credit cards that makes 'keeping the same card number' irrelevant.

I do not think this is an Apple issue, but a financial security issue that keeps Apple from storing that info as editable information. The requirement to renew the authenticity of the card info through the bank keeps the security up to date for your benefit.

Follow the steps in the support document linked below.

I misread this as an apple wallet card. I see the support for the iCloud payment info.
