LG smart tv doens't synchronise playlist

[richard36]

My LG smart tv (model: lg 55eg910v) can play audio via the spotify app and loads all the music added on the computer, however whenever i try to add songs to any playlist by using my smart tv it does not synchronise this action(they do show up temporarily after adding, NOT in computer application playlists). Whenever i restart my tv the songs are missing again and are also not showing up in the computer application.
