I am also facing similar issue and not able to login to PowerApps from Chrome browser.
Getting below error with normal E3 license -
Unable to obtain access token for resource 'https://service.powerapps.com/'. Error from ADAL.js: Token Renewal Failed (Token renewal operation failed due to timeout).
When I login with the Global Admin account, getting the below error -
Unable to obtain access token for resource 'https://service.powerapps.com/'. Error from ADAL.js: login_required (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 (login.microsoftonline.com). Trace ID: 03672664-a477-49b3-824c-2f95ad69d300 Correlation ID: 69031694-2843-4de9-a182-127aee9ace4a Timestamp: 2019-01-02 12:14:52Z).
Can someone suggest what can be next steps here - I already tried removing the cache with No luck.
