is it possible to change layer names on ArcGIS Online, instead of changing them in the original service? We try to avoid special characters such as spaces in layer names in services, which make the displayed names in ArcGIS Online look a bit strange to users.
In general, you can change the top-level name of a service that is added to a web map. if the layer has sub-layers (like in a map service), you can't change the sub-layer names.
