If your event has a Live Session button, you can click on it to be redirected to any ongoing session.
Once on the session page, you will find the Up Next box. From there, you will be able to disable or enable Auto-follow. Auto-follow will automatically redirect you to the next live or pre-recorded session.
If you choose to disable Auto-follow, you can also simply select the next session manually from the Up Next box.
Note: Once a Session is over and Auto-follow is enabled, videos will not automatically play once the countdown to the beginning of the Session is over. You may have to click on the play button for the video to start.
