Embedded PDFs not showing

[Ed_]

So I have a story map with embedded PDFs that show just fine. However, when the story map is embedded into Experience Builder, the PDFs fail to show. 

Why is that so?

How can this be fixed?

See the Embed widget doc :

The reason is because of the Chrome browser limitations and Embed compliance behavior, and other browsers should work fine.

The workaround would be to install an extension specifically for PDF, such as 'PDF Viewer'.
