Power Apps connection to SharePoint List

(1) ShareShare
ReportReport
Posted on by 5
In two of my Power Apps the users are getting a prompt to request access. However, they already have access to both the Power App and the SharePoint list it is connected to. But when I check the resources under the connections page, it takes me to a URL that doesn't exist on my site.
 
The Power App is connected to a SharePoint List. And in editing mode as Owner of the App, the connection works fine. However, when sharing the app to a User it says they need permissions. When I go to share permissions a prompt tells me that the user needs to have access to a resource. The resource it links to is the URL of the SharePoint List connected to the app, except it's incorrect. The URL in the sharing prompt appears to be generated based on the list name, and not the actual URL of the list. The SharePoint List connection is different, and is working fine in the App.
 
So far I have tried the following:
I've tried creating a new list with the URL that Power Apps wants to connect to.
I've tried changing the name of the SharePoint List to the name it was originally created as, hoping that would update the connection URL.
I've tried removing the connection, publishing the app, then adding the connection again and publishing the app.

    Glad you got that working - actually my fault I did not mention that (the suggestion I should have made was try Incognito/Private mode) - brain not fully in gear before keyboard engaged.

    The first screen showing the app access itself not available, are you sure the app is shared with respective users accordingly ?
     
    Try remove the datasource which is connected to datasource, save the app and refresh the browser.
     
    Try adding the new datasource which you want to connect, save and publish the app now try again. 
     
    If this also not working please revert back.

    If anyone else has this issue, the resolution was clearing cookies and temporary files. It appears that the PowerApp was caching an account that was previously logged in to the device, not the account that was currently logged in and the cached data was not being cleared even after restarting the computer or exiting and re-opening the browser. So while the account had access to the resources required, the cached account did not. Thanks for the reply, @WarrenBelz.

    I would have thought that your last action (removing and adding the connection/s) would have done the job, however obviously it has not. 
     
    As these seems user-specific, how is the List shared? If part of a Group, try sharing the List directly with the user (remove the old permissons) with at least Contribute level.
