Empty dataset

Hi all,

As of today one of my reports/datasets lost all it's data. When I tried to refresh the dataset it gave a cancellation error: 

Cancellation occurred when sending or receiving a request.

 When I republished the same .pbix file to the service and then triggered a refresh it worked like a charm. I recently started using the incremental refresh option for this report, whereas all other reports don't use that feature and also didn't lose any of their data. Could it be that there was a recent update to the web service that changed something internally in the way how these incremental refresh datasets are handled? If so, are there any patch notes for these changes so that we can prepare for such events? Do others also experience the same "issue"?

With regards,

Victor Molenaar
