How do I handle customer credit cards that get reissued or updated? Or what happens if a customer needs to switch cards?

​If the customer’s subscription is recurring, they'll see an update link option in their account page in MemberPress. Clicking that update link will allow them to enter their new card details. ​ ​If their recurring subscription is through PayPal Express Checkout or Standard, they cannot update through MemberPress. They'll need to update via their PayPal account instead.
