Grey box with web object
I have a number of videos embedded into a course that are being deployed through the LearnDash LMS. When I load the project into LearnDash, the first time I go through it when I get to the slides that have the videos on them I get the grey "web object" box. I can click on the web object box and launch the videos just fine. If I go to that slide again, the video preview image shows the way it should. How do I get the video preview image to show up on the first time the slide is visited instead of the grey web object box?
