On our ArcGIS Enterprise portal I have a number of Dashboards. We recently upgraded to Enterprise 11.3, and most of the Dashboards still open, and I can make changes and save again. However I have one Dashboard which when I open to Edit, it immediately has a blue dot beside the [Save] button.. as if the Dashboard had an edit that hadn't yet been saved.
When I hit the [Save] button nothing happens. When I try [Save As], I get a message saving "Could not save. Verify your credentials".
Apart from re-building the Dashboard from scratch, does anyone have any advice as to how to get my problem Dashboard to Save?
