jrsherwood I found a thread on reddit (link below) that says the displaying of the actual library name is platform Specific at the moment. NVidia Shield, FireStickTV, Windows (my setup), probably others too, do not this implemented, yet. Whereas AppleTV has the names in parenthesis.
I haven’t found anything, yet, about a time as to when the rest of the Plex apps/services will be updated.
I’ll post if I ever do.
