Just wonder what methodology applied to link between custom style file and understand vector basemap? Recently I used style editor tool on arcgis online to create a couple of custom style based on a local vector tile basemap. After a layer added or name changed on layer(s) on the vector basemap, the exist custom style is no longer working anymore until we create a new style. I hope that more consideration would be taken on existing custom style basemap. For example, for new added/changed layer, still show those un-impacted layers before create a new style file. Thanks a lot !
