A user is viewing a PowerPoint document in Vault that has the layout set to Speaker Notes (under PowerPoint Rendition Settings). Images that are seen on the source document are not appearing on the Viewable Rendition.
The images and/or text are removed in the Notes View on PowerPoint, but not in the Normal View. If the PowerPoint Rendition Settings are set to Speaker Notes, Vault renders what is actually shown in the Notes View. As a result, the images and text appear to be missing.
