Play on load as a playlist works ok the first time the ribbon is dropped for the page.  If the ribbon moves to a different page with, say, a single track as play on load, that track plays okay as well, but the previous page's playlist is still showing in the "now playing" but not 'active'. Moving the ribbon back to the first page with the play on load playlist, the single track from the second page stops playing, and it disappears from the now playing, but the playlist for that first page does not start playing again.
