I created a map service which contained domain and subtypes for the two included layers X and Y, then published to ArcGIS Online. I had forgotten to add a vital attribute to layer X to which I did (however at the time I did this I had already starting adding features to the map where I had 3 of the 7 subtypes displayed in the legend and hid the unused ones). After doing adding the missing attribute, then saved and re-share the map to the respective users all my other 4 subtypes disappeared. Now how do I add back these subtypes without having have to create a whole new feature service because I not have the time to remap all the data that already exist?
