I have the same problem, but with the Plex for Windows, and Plex Media Player (both of which are the latest version)…
Plex Movies & TV only shows up when I go into Plex Media Server.
Seems like Plex Movies & TV should work in other “apps” according to this related thread:
Oh, and yes, Movies & TV are enabled in Online Media Sources of PMS. But there doesn’t seem to be this option in PFW and PMP.
