Network mapped drives only show the name of the drive but do not show a disk icon (MacOS Ventura 13.1)
I am mounting a bunch of network drives that are listed in my login items. Even I just mount them manually this is all that I see - the names but no disk icon. You can see below that if you highlight the text it will just highlight an empty box. (I do have the setting checked in Finder Settings to show "External disks" and "Connected servers"
This is not a manufacturer issue. In the above picture one is a Synology NAS mount and the other is a disk attached to an Apple Airport Extreme.
If I open a finder window from the root all of the network drives do have an icon. They are only missing one on the desktop.
