It would be highly beneficial to have the ability to update vector symbol text directly in ArcGIS Online or enable a symbology sync option from ArcGIS Pro for AGO layers.
Currently, updating symbology requires several manual steps: modifying the symbology in ArcGIS Pro, updating the style file in AGO, logging into AGO, and then adding the new symbol from the updated style file. This process is cumbersome, even for minor changes—such as creating a new symbol based on an existing one with only a text modification.
Ideally, a direct symbology sync from ArcGIS Pro to AGO would streamline this workflow and improve efficiency.
