i have created a web map in portal for arcgis and based on the same i have created an operation view in operation dashboard. For a particular reason i removed some of the layers from the web map. But this causing a layer not found issue in the operation view. There is no way to change the layer configuration on operation dashboard itself. Is there any manual way to change the configuration file for this particular items, i mean an XML file or something. Anyone please help me through this.
