Online, go to 'Frames' once you have logged in. Select the frame you'd like to manage. In doing so, you will see all available playlists. Select 'Enable Playlist' or 'Disable Playlist' accordingly.
To delete playlists online after logging in at www.nixplay.com, go to 'Playlists'. Each Playlist folder has a Delete icon at the top right of the folder when you hover over that playlist. Simply hit the Delete icon if you wish to delete that playlist.
