Presentation Builder: Reconciling Your Presentation When Source Documents Have Changed
Presentation Builder recognizes when the source document you've built a presentation from has been changed.
If the source document that you have built a presentation off of has changed in any way, a red broken link will appear on the presentation in your My Items folder (1).
From any slide in your presentation, tap More (2), then select Open in Presentation Builder (3) from the dropdown.
Slides from the changed source asset will be delineated with red broken links (4).
Or, you may decide to keep your original slides, and dismiss the red broken links by tapping Clear Warnings (5).
The red broken links will disappear on the slides, as well as on the presentation in your My Items folder.
