Hi, I'm using the trial version of Rise to create a quick demo to show a client. I created some short lessons. When I preview, no Next button appears at the bottom to continue to the following lesson, as I've seen in demos. I was going to add a button manually, but my understanding from reading various discussions is that this is not needed, the next button should automatically appear. I checked the navigation settings for the course, and the previous and next buttons are set to On. What do I have to do to see the next button during the preview? I'm sure I'm overlooking obvious.... Thanks.
