When using real-time datasets from Azure Stream Analytics reports are not updated in real-time. Dashboards are updated in real-time, but not reports.
Streamed dataset will only update on dashboards when you use a "custom streaming data" tile which has very limited functionality. If you create a report from a steaming dataset and pin the report to the dashboard it will not update automatically. I would be happy just to have the option to set a regular refresh but this option is not allowed when streaming data is used.
