Does Plex Format change on different clients?

I’ve got several clients with Plex Player and are seeing different “looks”. Plex on a Win 7, XBox1, and Ipad are giving me the same content but after finally finding an add-on for Kodi on an Openelec Pi, I’m only seeing Music/Other Video/Photos/TV Shows. No Channels or Playlist. Content in these Libraries seems to be the same, so I’m sure I’m corrected to the sever… Is this a limitation of the add-on? I’ve tried to make sure I’ve got the best add-on, and am beginning to wonder if the Pi is going to be a viable Plex client.

  1. the Kodi add-on is not finished yet.
  2. There are already 2 other Plex clients for the Raspberry Pi with full features: PMP embedded and RasPlex
