Have the same problem on ElegantThemes Divi Theme where I can't get anything else than a featured image or both featured image and video below.
Also another dumb question, how exactly should I write the short code in my posts to get it working? Have looked everywhere and can't find a single example which I think is rather strange, most people probably know but for a novice and first time wordpress user its not as easy :)
Should I do it like this?
Or some other way? :P
