I have created map services in ArcGIS Server 10.2.2. In a couple of these services I need to make symbology changes to the layers in the mxd. I am unable to see these changes unless I delete and recreate the map service. I am not adding or deleting layers, just making changes to the existing layers. I understand if need to go through the process again, but in earlier versions I just had to restart the service or in many cases the edit showed up automatically. Thank you in advance for your input.
