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)
Hi all,
I encountered the exact same issue this morning. Appears to be a recent bug but there is a workaround (answered in link below) which I've tested.
If you remove the title of your visual in your report and republish it, you will then be able to pin the visual to the dashboard.
