As of Oct 2025, ArcGIS Hub allows site admins to set choose how a layer is symbololized in Hub at the layer level. This means if an organization prefers to use their own symbology across multiple sites, potentially with hundreds of layers, they will need to visit each layer in each Hub content library and change this setting manually.
Please add one of the following options at the Hub Site level to make it easier to set the original symbology as the default.
Option 1) Have one setting at the site level to choose between Hub symbology (the blue) or Original symbology. I guess in this scenario there will be confusion with the layer level setting, so maybe that should be disabled if the site admin elects to have native symbology
Option 2) Add a setting at the site level that defines the default option to one of the two choices (Hub or Original). Any layers added to the site after the setting is applied get that default option applied. This means owners of existing sites would still have to go through all their sites and manually update their layers.
Option 3) Add a button at the site level that allows the site admin to run a one-time process to set all layers in the Hub content to one of the options.
I think Option 2 and 3 are probably the easiest to implement given there is a layer level setting. And I think both could actually be implemented together and be great compliments to each other.
