I got a Office 365 E3 plan by my company. I created a mobile Apps with PowerApps 2 weeks ago. But I can't access PowerApps Web Studio stably for many days now, which frustrate me a lot, it also stop me from introducing this solution to my associates. The Web Studio often requests me for Identity Authentication again and again, with the error message : 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). Except the poor experience of Web Studio connection, PowerApps is a great low-code application solution for my SharePoint list in terms of easy coding syntax, friendly interface, connection to many types of data source and integration with Power BI. If can lauch the PowerApps sudio in my laptop like the Visual Sudio, it will be perfect!
