When I right click, the option shows up for my Inysnc folder but does not appear for any of the folder outside of that one.
I would like to upload a screen shot but as a new user, I am not allowed.
@kris_cee: Is your main Insync folder set up on an external/network drive? If so, “Add to Insync” context menu option would not be available for you. This is so because presently, it relies on Windows symlinks which can’t originate from a network drive.
