SharePoint embedded folder in Power Apps suddenly gives a 401 UNAUTHORIZED error

[Provsten]

Hello, 

We are using an iFrame in a Power Apps model-driven app to display a SharePoint Online folder in context of the record. 

This approach has been working fine for at least a couple of months but suddenly we are getting an 401 UNAUTHORIZED error in the iFrame. 

The user can open the folder in a new tab without any issues. 

Does anyone know if anything has changed in SharePoint that could affect this approach? E.g. something regarding authentication or similar?

BR,

Niels

SAME CRITICAL ERROR

Same here

WORKS IN CHROME AND FIREFOX BUT IT MUST WORK IN MICROSOFT EDGE

Also getting a similar issue, but it's with images. I can open the isolated images successfully in a new tab, but otherwise it's throwing 401s.

Maybe this has solved itself.

The solution for us was simply to Reset Settings in Edge. That fixed the issue for all users.
