I am working on creating a operations dashboards for a project. I noticed this week that if I use the symbol clustering function on a layer in an arcmap online (on our agency portal site), when I create filters they will not correctly display the clustered data on the map. i.e. If I create a filter to for userIDs and filter the data by userID = '1120', other userID reports will still display. If I don't use the clustering symbol function in the online map, then when I filter only userID '1120' reports display on the map.
The charts I created filter correctly in both situations.
