I have an AGOL webmap that originates from an ArcGIS Server (AGS) mapservice which has been in operation for several months. Last month many new layers were added to the mxd for the mapservice and these layers appeared in the webmap after the mapservice was republished. More changes were made this week and after republishing the changes were seen in the mapservice's REST endpoint, but are not seen in the webmap.
Has anyone ever encountered this scenario and would know how to fix the problem?
