For reasons of travel, forget my data registered in the family plan. I do not want to change account, the question is: Can I cancel the current family subscription and re-register with the same account? In order to update my address.
It’s not possible to change the address registered on an existing Premium for Family plan.
If you move, or enter the wrong details, you need to create a new account (make sure you cancel the plan on your old account beforehand, and sign out everywhere) and subscribe to Premium for Family on that new account.
