When creating a dashboard some widgets will be hidden for certain users. The outline of that specific widget (report) is then still visible with the message stating it is not accessible. The widget should not be there at all. This results in the dashboard looking incomplete and I do not want questions from the blocked users as to why they cannot see certain widgets.
As a quick fix I have had to create a copy of the dashboard. I think the best solution is that the widget is not visible at all for those who do not have access to it.
