The previous version and the new October version of PowerBI desktop hangs when publishing reports to the Power BI portal. The report gets published sucessfully but the "Publishing to Power BI" dialog never finishes. Clicking on cancel or close on the dialog does nothing. The only way to get out of PowerBI desktop is to use task manger and kill the PowerBI process.
It is like PowerBI desktop gets stuck and the portal doesn't tell it the report and dataset is done publishing.
