Hello @TomDePuyt
I am trying to import the S-57 cells to the Maritime Geodatabase and getting a symbology as shown below.

I am not the getting the ring symbology as it is shown in the below image.

I am getting this ring symbology while only using the ArcGIS Maritime Server extension and not in ArcGIS Pro. Can you please let me know that what's the reason for not getting the ring symbology in the ArcGIS Pro Maritime Desktop Extension.
Your guidance will be of great help.
Thank you
