Visio Viewer displaying blank pages in Service

Hi  olimilo ,

You should be aware of the following sign-in issues:

• Visio Visual in Power BI Embedded reports   A Power BI report can be embedded in apps such as Microsoft Teams or third-party apps. These apps can block pop-ups such as a sign-in prompt. In this case, the Visio Visual file needs guest access permission in SharePoint Online and OneDrive for Business. Otherwise, Visio Visual keeps prompting to sign in but the app will keep blocking the sign-in pop-up. 

• Single Sign-on authentication    Visio Visual in Power BI needs access to the Visio diagram you're working with, which means you might see a sign-in prompt. In cases where Power BI user sign-in information can’t be accessed through Single Sign-on authentication, users trying to view the Power BI report might see a sign-in prompt to authenticate themselves working with the Visio Visual.

• Internet security zones    If you're still having issues with authentication while working with Visio Visual using Internet Explorer, you may have Power BI and SharePoint in different internet security zones. Add both the Power BI domain and the SharePoint domain to the same security zone in yourInternet Options and then try working with the Visio Visual again. For more information, see Change security and privacy settings for Internet Explorer 11.

You may refer to this offical blog to learn more details. And you can follow this video to create Visio Viewer.
