I would first like to understand the scope of changes to saved recipient details. Which future payments created after the update will use them, and does an update affect instructions already created but not yet executed? For related transfers already submitted, through which official channel can the details used for each be confirmed, and is a separate correction request needed? Please distinguish a successful update to saved details from a successful transaction correction. I am not including account values or verification codes, authorising changes or payments, or sending a duplicate transfer because the status is unclear.
