I have created a map using ArcGIS Online that consumes a REST service elevation raster which I have rendered using a elevation color ramp and enable dynamic range adjustment. This all works fine on the computer and if viewing the map via a browser on the phone. When I try to use that map in the Explorer App however the raster returns to the same symbology it loads with from REST service. Is there anyway around this? I'd like to have students use the Explorer app rather than just a browser window.
