I created a web map in my AGOL content folder after publishing from ArcMap as a Portal feature service. I created a web map in AGOL by bringing in the service URL. I have three group layers with several layers within each group. In the AGOL map viewer, I went through each layer and configured the popups and symbology. After I had done this, I needed to add a new layer to one of the groups, so I added it to my MXD group layer of interest, republished the service and then went to the web map that is fed from this service. The web map doesn't update with the new layer, so I was trying to figure out how to update the web map without having to recreate the entire thing in AGOL? I don't want to really do this each time I have to add a new layer in the MXD because of the configurations I have on each layer with the popups and symbology. Am I missing some process/option to refresh the TOC so that it adds the changes I made to the service?
