I have WSA Ver. 18.104.22.168 , OS Catalina Ver 10.15.6.
I like to offer a suggest on the Advanced Setting/Scan Setting / Scan Options page.
I think it would helpful to most users and especially new users (like me) of WSA that next to the Options:
"Automatically scan removable media" (Add a desc. of types of devices here)
"Scan mounted Drives" (Add a desc. of types of devices here)
examples (NAS network attached storage) (Thumb drives) etc.
Everything can be removed and everything can be mounted so it is a little confusing at least for me.
