If you publish a presentation that contains SmartArt graphics while in the Slide Sorter View, none of the SmartArt graphics will appear in the published file. You can workaround this by changing the view in PowerPoint to normal by using the method below:
- In PowerPoint, click the View option from the menu.
- Select Normal.
- Republish your presentation.
After changing the view to Normal, the SmartArt graphics will publish as expected.
