First, please ensure you have already registered for a session here.
Once you've registered, await the confirmation email which will contain the link to access the materials and to join the webinar on the day itself. You will also receive reminder emails 1 day and 1 hour before the webinar session. The "Join" button in these emails will lead you straight to the webinar session (see image below).
Webinar sessions usually open 5 mins before the start time. In case you join the session early, there will be a prompt displaying 'The Training Has Not Started' - please stay on the page till the webinar starts.
