Nothing wrong with that code. It works fine in a blank Revolution Slider page. Except that Newspaper throws a hissy fit when I try to edit it with TD Composer on the front end. Also, it is probably the Revolution Slider that is throwing the error on mobile, but as you can see here (if you are using a desktop or laptop) it works fine.

working embed

I shouldn’t have to use Revolution just to get a fairly simple embed to display. So, you tell me how to create a completely blank Newspaper page to embed the code on.
