Error when starting up PowerApps studio in browser

I can't seem to open browser version of PowerApps studio. I can log in and see my apps no problem, running them works fine as well but when I go to open up the studio in browser I get an error. I have tried this in Chrome, Chrome Incognito, Internet Explorer, Edge, and Edge InPrivate. It fails to open in all cases. I have also tried restarting and on another computer and neither of those work either. The error that PowerApps reports to me is one of two:

WebAuthoring abnormal termination.
Client date/time: 2017-01-22T07:14:01.857Z
Version: 2.0.574
Session ID: 7c2b2503-8a5e-a560-6c34-4ba666e1f225
errorMessage: Script error

OR

WebAuthoring abnormal termination.

errorMessage: Uncaught Error: Core.ApplicationError: [InvalidAuthenticationResult] AuthenticationResult is not valid. Error: Failed to parse the WebAuthenticationResponse.

I have also opened up the debugger in Chrome to see if I could get any extra info and this is what I pulled from the console:

I normally run PowerApps in the desktop version so that works fine but It would save a ton of hassle to be able to run two instances at once which cannot be done with Windows Metro apps. I've looked into hacking that to get it to work but it doesn't seem to be a simple endeavor. Let me know if anyone knows of any way to get more than one instance of PowerApps working on one computer.

Hi Justin,

 

There is a similar issue on another thread, the thread link is:
https://powerusers.microsoft.com/t5/PowerApps-Forum/App-not-starting-from-web-player/td-p/17322/page...

 

But it seems that this error “WebAuthoring abnormal termination” when open PowerApps Studio for Web has been fixed now, could you tell me your location?
Could you please try to clear the cache of your browser to see if it works?

 

Best regards,
Mabel Mao

Hi Mabel,

 

I just tried clearing my cache on Chrom and Edge I continue to get the same error. I am working with a team of two other people and none of us have been able to get the web editor to work. We are located in Saskatoon, Saskatchewan, Canada.

 

I greatly appreciate any help you are able to offer on this issue, having a web version of the editor available to us would be incredibly useful.

 

 

Thanks,

 

Justin

Thanks for your feedback. We are aware of the issue and we are planning to fix it in the future releases. please meanwhile use studio for windows.
