DoubleDutch's platform uses a container structure in the mobile app. This means each app can contain multiple events.
To view other events that you have access to (past, present, or future), tap on the three dots in the top right-hand corner. Then tap on 'Switch Event'. You will then see a list of events; tap on the event name to view that event's content.
Alternatively, you can log out of the app completely by tapping on the 'Logout' button at the top of the "Select Event" screen.
