I have a relatively simple Power Pivot table I've added to the Power BI service via Sharepoint.
When I open it in Excel 2016 and refresh on my desktop, it works fine.
When the service refreshes it though It always returns once you try to interact with it - click on a slicer or filter for example - and both the service, Excel Online, and Excel 2016 give this error:
the pivottable report is invalid try refreshing the data
Opening it up in Excel 2016 and refreshing fixes it, but the error comes back again on the next scheduled refresh from the service.
Any ideas?
