You may notice that your chosen media is not playing in your storybook project. At this time, your interactive media won’t play within the storybook or preview until you’ve published it. In order to see the interactive media play, publish your project and wait for it to render the links to your storybook (this takes about 15 minutes).
After you publish, if you’d like to edit your project in any way, go to “Published Storybooks” or “Purchased Projects” from the left-hand menu. Find your project and click “Update Digital Content” from the “Project Options” dropdown menu.
