    Although ArcGIS web app optimizer behind the scenes uses the same dojo build system, it runs at least a twice slower. But the most unpleasant thing is it puts a building task in a queue with the “Your build has been queued and will start when resources become available. Feel free to close this browser tab; you’ll receive an email when the build completes.” message. It seems that the queue never comes to an end. After the task gets status ‘Queued’, the next build task will have the same status, even the first one was canceled. In such way it is impossible to create any build because of the queue. I tried to create a build using ‘ArcGIS web app optimizer’ on Friday morning. The task was put to queue again. On Monday I have to cancel it because it was still in queue. Then the ‘ArcGIS web app optimizer’ put in queue each build task I tried to create. Further it was impossible to create any build by ‘ArcGIS web app optimizer’, even the simplest.

    Please, help to figure out why the ‘Queued’ status appears and how to cancel it to create a new build.
