I am trying to setup a default view for ArcGIS Earth for a customer in another country. I want to configure ArcGIS Earth to open to a default MapService and basemap already configured so they don't have to try and figure out how to step through and pick out a basemap. We have a bit of a language barrier. I have been looking at the config.xml, and I have tried to put in my MapService into the startupLayers section. I have also tried to put it in the organizationalBasemaps section without any change. Are there any other step by step instructions with some fictional examples on how I would configure this file available?
