I need to update the symbology for a web map I have published to my portal, and I was having trouble doing that. I checked the Server REST endpoint for the layer I need to symbolize and I noticed it already had the changes I wanted to make, but they were not reflected in the symbology of the web map. I suspect it is related to editing the symbology on the layer in the portal map viewer and saving the layer visualization there.
I want to change the layer symbology shown on the web. I can attach screen shots of the REST drawing layer information and the symbology on the Map Viewer to show they are different if needed.
