I've found that most of the layout from feature templates set in ArcMap carry over to ArcGIS Online. However the ordering of symbology per layers is not being honored. I have a layer for instance, that has a few dozen different symbols that it could be displayed as depending on the symbol field value. In ArcMap (10.2), the names corresponding to the symbols are displayed in alphabetical order for ease of finding and using them while creating new features. But when the Layers are published as a feature service, the ordering seems random within a webmap. Am I missing a step here or is a known issue?
