Sharepoint list connector intermittently failed to connect

Our Team has PowerApp that is linked to a SharePoint list.


Since Later Afternoon on Tuesday August 13, App has been experiencing intermittent SharePoint list connectivity issues.


Issues Observed:

- No items visible in Gallery

- Content of drop down menus was not pulled from SharePoint

- Edit Forms were not saved to SharePoint list correctly (error 'There was a problem saving your changes. The data source maybe invalid.'.

- No changes were made to the app itself. Troubleshooting consistent of reconnecting SharePoint lists, and republishing the app. Issues are somewhat intermittent.


They are causing the app to be inoperable which is having a major impact on our work. I've seen other groups highlighting similar issues.

Re: Sharepoint list connector intermittently failed to connect

Hi @v-tkmasz ,


The reason of  "The data source may be invalid" may be many possibilities.

Would you please check if your data source is connected successfully in your app? 

Could you show me your formulas and screenshoots?

Is this issue happening to all your users and in different devices? Please try to test with different web browsers and mobiles.



Recently, there seems to be an issue with SharePoint connections for MSIT users. We are aware of this. If there is any update later, I will notice your here.
