Editing a card after leaving family sharing
I just left family sharing/ family subscriptions. But, the card that is used in family sharing is still there if I edit the card information will that change it for everybody?
iPhone 12, iOS 17
Are you the Organizer and you turned off purchase sharing? If yes then nobody else has access to the card except you.
Add a family member to your shared subscriptions - Apple Support
"If you're the family organizer and you don't want to pay for family members' purchases and subscriptions, you can turn off Purchase Sharing [ How to share apps and purchases with your family - Apple Support ]. When Purchase Sharing is turned off, everyone must use their own payment method. When Purchase Sharing is turned off, family members can share subscriptions, but they can't share individual purchases like apps or books."
If you have left a family entirely then you have no access to purchases made by others and there's isn't really any connection between your purchases and purchasing ability and theirs. A bit more about leaving a family in Leave Family Sharing - Apple Support
