In ADE I'm unable to see the content of an EPUB3.0 file exported from InDesign that has Edge Animate .oam. I only see the cover, please help.

Exported an EPUB 3.0 file form In Design with an Edge animate .oam (some text, a .png, a play button and an .mp4). However when I try to open it in Digital Editions I see only the cover, clicking on the actual page does nothing, only white page.

I managed to open it with epub file reader where the content is visible and the button and video work, but I want to use it on an ipad, so i'd like it to run on ADE if possible. Any suggestions?  Thanks
