@striker2550 "To change the card on a PayPal subscription, log in to PayPal, go to Settings (gear icon), select Payments, and click Manage automatic payments. Select the merchant, click “Change” next to the payment method, and choose a new card or link a new one. "
Or you can do what you say, but actively updating your payment information through PayPal is the better way. I think it nets out to less effort on your part.
