Before the system was updated to its new look you could easily cancel on demand webinars or amend the end date for these webinars but now it doesn't work.
Anyone found a way to do this successfully?
Sorry about that.
We are working to improve the messaging there, but what you're seeing is a precautionary behavior so anyone in-session would not be kicked out. You should be able to change the end date of the on-demand webinar to today, and then the session will expire after midnight.
