Unable to load data in my powerapp from the sharepoint list

My App can work and able to connect to the data source sharepoint list on PowerApp Studio but not in the mobile app. When open the App, there is an error in red on the top"Failed to load xxxxx. An unknown error occurred."

Please advise. Thanks.

Hi Mikki,

 

To reproduce this issue, please provide information about:
1.What’s the version of your mobile device?
2.Do you have other Apps based on other connections? Such as OneDrive, Drop box, etc., when you run these Apps on your Phone, do you get the same error message?
3.Do you try to open your Apps on another mobile device to see if it works for you?

 

I have an App based on SharePoint Online list, and the version of my iPhone is iOS 9.3.5, when I run the App on my phone, no error message occurs, and all the data can be displayed and I can write back to data source.

I encountered isssue on iPhone 6 Plus and iPhone 7 with iOS 9.3.5 and 10.1. My colleagues who were working on different PowerApps encountered the same. The Apps can load data at the beginning but not after a few days. Other data sources, excel and common data model, can be loaded properly.

I and my colleagues just have problem in the Mobile. And we are working on different Apps that link to Sharepoint online list. There is data loading error when opening the Apps. In PowerApps studio, they work fine.

Having a simlar issue here. I created an app from a Sharepoint (Office 365) list using the web app at first, then using the app on my Windows 10 PC.

 

It worked on iOS for a few tries, but now it just comes up with a black screen and eventually says ""Failed To load Phone List, An unknown error occured."

 

Another user with Android works fine (for now), and it works fine in the desktop PowerApps development app.

 

I've logged off on my iPhone and back on, but that didn't help. The sample apps provided work fine on the iPhone.

 

Any suggestions? I cannot roll this kind of thing out if it is this fragile. It is a super simple phone list with 4-5 columns of data and minimal customization from the defaults when I created the app.

Sorry for the troubles you are experiencing.  Could you provide the session ID?  iOS PowerApps version 2.0.540 should be in the Apple store any day now in which you can find it in menu > Session details.  If you don't want to wait, you could capture it via a network trace on any GET or POST request to azure-apim.net or management.azure.com (look for the x-ms-client-session-id request header) but it's a bit more involved.

 

Thanks!

Well, I got the new version this morning and unfortunately from a bug testing perspective, the upgrade cleared up my issue. But I do see where to get the session ID going forward should it happen again.

Glad this is resolved for you.

 

Thanks,

Chris
