I've published an image service of a LiDAR digital surface model (DSM) that uses a raster function to default to a shaded relief view. When added to an ArcGIS Online web map, I'm not getting access to the renderer dropdown menu to switch templates. I'm following the steps here, but clicking More Options (Step 3) does not give me an Image Display menu item to access the renderer. I had this working once before and don't know what is different this time.
Thank you for your help.
