How do I reorganize a playlist's content, scheduling or displays?
Go to the Playlists menu item, then My Playlists. You'll see all of your playlists and their status: if it's currently playing or paused; if it's active, scheduled to play in the future, or expired (past its scheduled date and time); and if it's locked or unlocked.
To edit a playlist, click the teal menu icon to the right of it. You'll see options to lock, edit or delete the playlist. Click "Edit playlist".
