Hello,
I have a Powerapp that uses SharePoint as the backend. There is a list in SharePoint with users names, that are used to determine permissions in the app. However, some users have a different name in SharePoint than it displays in Powerapps and as such when the app loads, their permissions are not taking effect. Eg: In SharePoint someone can be named John Doe, but in Powerapps it shows their middle name - eg: Marlon Doe, so it looks like a different person to the app, and blocks them from accessing relevant screens. I am not sure what fix to include here to allow consistency across both platforms. Any feedback appreciated.
