Because updating documents in Interfolio requires deleting them and re-uploading them and because Interfolio does not allow users to modify or delete files that were uploaded by other users.
Because the collaborative features of Interfolio are limited, extra communication is necessary between admins and candidates when trying to work together on case documents, so we recommend waiting until documents are finalized to put them in the system.
