If a customer has multiple payment options (e.g. credit cards, PayPal, or others) on file, and the default payment option fails to be renewed upon the subscription’s auto-renewal, we will not try to attempt to charge the other cards on file.
Only the payment option that is associated with the subscription (the default one) will be charged. The user would need to update the subscription with a different payment method in the My Account section to start charging a different payment method.
