We have a map service published on a stand-alone ArcGIS Server 10.9.1 using the ArcGIS Pro runtime. When using version 430.1 of the ArcGIS plugins for AutoCAD in AutoCAD Civil 3D 2023, we can add the map service using the "Add Data by URL" as we could before with earlier versions, but now it only displays the default visible layers defined in the service.
When accessing the Contents panel, only the layers at the root level are displayed. There are no arrows (to the left of the Group layers checkboxes) in the interface that would allow us to click and expand the Group layers to view their sublayers.
Also when we check or uncheck the checkbox of any Group layer at the root level, it does not change the visible layers in the map. Using Fiddler I can see that an export request is generated when checking or unchecking a checkbox, but in the request body the value of the "layers" parameter does not change, no matter what layers we check or uncheck. The image rendered is always the same.
Is ArcGIS 10.9.1 still supported for this version 430.1 of the plugin? The exact version of the plugin is 430.1.25.1
Thank You
