We have setup Portal for ArcGIS 10.3.1 and deployed a single window Operations Dashboard. When I launch the Web version of Operations Dashboard, I do not get the option to change the theme. Also the Expand and collapse button that should come at the lower right corner of the panel does not show. When I check in Google Chrome Developer tools, it shows an 404 error - Failed to load resource: the server responded with a status of 404 (Not Found) ... http://xxx/arcgis/apps/dashboard/js/dashboard/img/expand16.png
