How do address defaults and address removal work?
In Addresses, each saved address shows whether it is the Billing default or Delivery default. Select Set as billing default or Set as delivery default to change the corresponding choice.
Select Remove address to delete a saved address. Existing orders keep the delivery and billing details they already have, so removing an address does not rewrite those orders.
An address carrying Delivery change awaiting review cannot be edited or removed while that review is pending. You can edit or remove it once the review is complete. If a current order needs correcting sooner, contact the team. You can still choose a different billing or delivery default where appropriate.
