We have a PowerPoint file stored in OneDrive and sharing is set to "anyone with link". However when this is embedded into a webpage there is a request to "Sign In" and signing in will allow the iFrame to display correctly.
We would like the PowerPoint to display to all users without a sign in.
The iFrame is hosted on a separate domain.
Can anyone provide guidance on what is causing this issue and possible solutions? Is this related to CORS?
