There appears to be a bug when pinning visuals to dashboards. It seems to work for table/matrix visuals, but no for any other type (the visuals in the gif are standard PBI visuals)
I am also experiencing this recently.
I created reports and visuals on PowerBI desktop app and published it to PBI service. When I go to my PBI Service report, chose a visual and tried to pin it to a dashboard, the following window pops up:
It does not show the visual preview as it usually does, and when I click "Pin" nothing happens. This is happening to bar/line combo charts and gauge chart. I can still pin card visuals no problem.
Please help resolve ASAP. Thank you.
