Power BI Paginated Report embedded as a web part on SharePoint Online sign in issue on mobile device

[SteveNeshausen]

We have a Power BI Paginated Report embedded as a web part on SharePoint Online using a EM1 capacity workspace. On desktop we have to click 'sign in' for the power bi report to authenticate and run. However on any mobile device the 'sign in' does not work and continually just says 'sign in' via SharePoint Online. Logging into the Power BI app on the device works fine it only appears to be an issue through the SharePoint online web part. Any help much appreciated.

Hi @SteveNeshausen ,

When you doesn't embed a Power BI Paginated Report, could you sign in the SharePoint online web part?

Do you have multi factor authentication (MFA) set to required?

Here are some advices that worth trying based on my researching:

1. Clear cache of SharePoint app. Usually, you can clear cache in your Setting>application>SharePoint icon.
2. Embed a report web part in SharePoint Online  
3. SP Mobile App: Couldn't connect to the service 
4. Solved: Mobile view is not being shown for embedded powerbi report 

If the problem is still not resolved, please provide detailed error information or the expected result you expect. Let me know immediately, looking forward to your reply.

Best Regards,
Winniz

Thanks you for your reply.

I have tried above but with no change unfortunately.

We do have mobile responsive power bi embedded reports on external websites working fine, these use azure 'app owns data' credentials for any internet user to access the reports.

This issue is isolated to our organisations sharepoint online where our users are authenticated. On the page in question we have a standard power bi web report part which authenticates fine and user can view. The other report is a generic web part as it is a 'paginated' power bi report (which cannot be embedded in a power bi sharepoint part). On the desktop it presents us with the 'sign in' power bi splash screen we click it and it authenticates and shows us the report. On mobile sharepoint online however we can continually click the 'sign in' and it does nothing.
