Error with a Power App embedded in Power BI in Mobile

[Avih]

Hey,
I have a Power App embedded in Power BI, the app works perfectly on web but fails on mobile.
In my first screen I have a Gallery which shows data from a PowerBI Integration (This is working in both the web and mobile).
Then there is an option to press "Edit" for a given row, which lead us to Screen 2 where a Sharepoint List is being used, when moving to this screen in mobile I get a "Sign in required" message, when pressing "Sign in" I get a "Error when trying to retrieve data from the network" error.

What can be the issue? given it only happens in Mobile and NOT in web. I have tried it from a different mobile also, same error.

Thanks!

EDIT:

I just realised that when I'm adding a gallery with the data from sharepoint list in the first screen, I recieve the same problem, meaning that it has something to do with the sharepoint list for sure.
Any suggestions?

Apparently the problem was the premissions that were set in a mobile use in the Sharepoint List.
Thanks for the help.

Thank you, @lbendlin , for your response.

Hi @Avih,

We sincerely appreciate your inquiry through the Microsoft Fabric Community Forum.

Based on my understanding, since Screen 1 with Power BI Integration functions properly on mobile devices, the issue appears to be specific to SharePoint List access. The errors indicating "Sign-in required" and "Error retrieving data" on mobile devices suggest an authentication or network-related issue with SharePoint.

Kindly follow the steps mentioned below, which may help in resolving the issue:

1. In Power Apps Studio, ensure that your SharePoint List connection is active and that you have the required Contribute permissions.

2. On your mobile device, enable third-party cookies. (For iOS: Navigate to Safari settings and disable "Prevent Cross-Site Tracking"; for Android: In Chrome settings, allow third-party cookies.) Additionally, clear the Power BI app cache and sign in again.

3. In Power Apps, add ClearCollect(SharePointCache, 'YourSharePointListName') to the OnStart property of Screen 1 or to a button. Use SharePointCache as the data source for Screen 2 instead of the live SharePoint List. Thereafter, republish the app.

4. Open the Power BI mobile application, test both screens, and verify if the issue persists.

Implementing caching helps in avoiding live SharePoint calls on mobile devices, thereby bypassing authentication or network issues while ensuring that your application remains functional.

This was never supported and likely never will be.

If this was the case, I would imagine that the first screen, with the PBI Integration wouldn't work either, but it's working.
Only when preceding to screen to with the integration with the sharepoint list, this is where it shows the error.
