There can only be one active session at a time. A session is considered active if it's in status 'uploading' or 'processing'. If a session is not marked as complete within 30 minutes from creation it will be marked as 'expired' and a new upload session has to be created. Same upload session can be used for uploading multiple transaction batches on multiple accounts on an organization.
