I have an embedded PBI report. The application has its' own filters and granularity for time (monthly/yearly/daily/ etc.).
The custom tooltip for one of the visuals doesn't perform correctly when changing granularity. It shows broken data like NaN, Total instead of Category name and (blank). The bug disappears after a page refresh. But if the granularity changes again the bug will appear immediately.
I've checked tooltip functionality in the Desktop and the Service. It works correctly for all filters/granularity/time intelligence without delays.
