My chase sapphire card number was stolen while on vacation out of the country before covid. Reported the fraudulent charges and got a new card and number. Recurring subscriptions transferred for about 12 months then I had to update the card number. I’m not a payments expert but presumably the subscription is tied to some authorization and not necessarily the number itself.
