It seems on my Mac and iOS phone and tablet that the 8th magnitude C component that is correctly described in the information panel for Iota Cas is not shown in the sky map.Only the mag 4 and mag 6 A and B components (with 2.5" separation) appear on the map. The C component that is described as being 8" away is not shown.
I'm running SSP6 on a Mac running Catalina 10.15.7, and my iOS devices which are running iOs 14.1.
