Hello there.
it is possible in the AU220013 Mobile workspaces screen to choose dasboard widgets and add them to a worspace, but when you click in the Widget tab of a workspace, on the dashboards column, some dashboards are not visible.
I haven't found what the criteria is that makes a dashboard usable on that screen. It doesn't seem to be the ExposeViaMobile checkbox in the SM208600 screen, nor the fact of adding the dashboard screen in a customization project (in the mobile application menu). But then how do we do it?
