The new "Save Layer" feature makes it easy to update symbology for a layer across all the webmaps where there is not custom symbology defined. However, there is no way to use the same function to update the symbology of a view layer derived from a parent feature layer. This is inconvenient when view layers are used mainly to control privileges vs. to define styles/filters.
Add the ability to re-link the view layers with their parent layers to the Map Viewer and/or Visualization Tab.
