When you are in this section click on "My Enrolled Events" and the events you have enrolled into will appear (in all views). "My Waitlisted Events" You can click this toggle to view events on the calendar if you're enrolled in any fully booked event and also waitlisted for it. Toggle the option "Event With Positions Available" to display events where positions have opened up for any fully booked event you've enrolled in.
Here you can review the event details or unenrol from the event.
Note: You will need to search by months if the event is not in the current month.
