The viewing of recordings must first have been authorized by the activity organizer. It may be that despite the authorization, the viewing period allocated has expired. Validate this information with your organization or school.
To view a recording, go to the “My activities” section of your Via home portal. Browse the calendar, if necessary, to find the right date. Then click on the title of the activity whose recording you wish to view. To view your recording, simply click the playback button at the right of it.
You could also use the same invitation email to the activity. Although the latter has ended, the “Access” link should now be replaced with “Recordings”. Then click on the “View” button of the desired recording.
If the activity in question does not appear in your calendar, contact your organization.
