PowerApps Can't find app or open existing app



I am receiving the below message when attempting to edit an existing PowerApp linked to a SharePoint list. I have tried the following provided solutions and it still has not fixed my issue:

  1. Clear my cache
  2. Edit PowerApps in browser (Open in incognito or private mode)
  3. Restart computer
  4. Remove PowerApps and download newer version of app

Would someone please assist?

This looks like the cookie-blocked problem:


"message": "Unspecified error has occurred. Error: Authentication failed. Please ensure your browser allows third-party cookies for the domain \"\". ADAL acquireToken failed for resource '': AADSTS50058: A silent sign-in request was sent but no user is signed in. The cookies used to represent the user's session were not sent in the request to Azure AD. This can happen if the user is using Internet Explorer or Edge, and the web app sending the silent sign-in request is in different IE security zone than the Azure AD endpoint (


Thanks for the response, I have looked at all internet browsers to ensure that cookies are enabled. The issue is still unresolved.

@AndyPennell, thanks for the response. This was my first step. I have already completed all of these steps and am still experiencing the issue.

Also if it helps, when I attempt to load from Chrome I receive the below error. Just an FYI, I am able to open the app, I just can't edit using IE, Edge, Chrome or the PowerApps App.

Still unable to access my app. Does anyone have any additional thoughts?
