How to ensure powerpoint macro is displaying slide from latest file version.

[Stacy Ajouri]

Using Office Powerpoint macro configured to display a given slide in the file.   When the file is updated and saved the latest information is not displayed until a Ctrl Refresh is forced in the browser.  A simple refresh does not update the content.

Behavior is independent of update method:  either upload of a new file or edit in place using the companion app.

Although the macro does not show latest,  the ppt preview is updated with a simple reload page (either browser refresh or via the popup from confluence.

How do I ensure the page renders the latest information to the visiting user without requiring a manual forced refresh of the page?
