The screenshot below demonstrates what is happening. It looks as though what used to be the preview pane has turned into a terminal. I believe Katacoda may have changed the way they want users to embed scenarios as seen here on their (website) [https://www.katacoda.com/embed] so that the preview pane is now a terminal. I'm hoping that maybe all we need to do is update the way we currently embed the tutorial.
