When a client completes all of his/her selected videos in their Portal, an email will be sent to the system user who invited them and they will be shown in the completed column on the Client journeys page.
Clicking on the client name will take you to their journey report page where you can see all the details about their viewing journey and any questions they asked.
Using the 'Downloads' button in the top right you'll be able to download a PDF copy of this page for your client archive.
