If you cannot see the webinars in which you have enrolled, under "My Courses", please navigate to the "Dashboard" (link on the top menu of the page) and select the webinars from there. When you click on their name you will be taken to a screen where you can self-enrol to them.
After doing so, you will be able to see the webinars under "My Courses" and receive all the related notifications.
Thank you!
