Tracks that Apple Music 'Matched' are not playing via the Apple Music Sonos App. In the Sonos app, when I browse to Apple Music->Artists->Album->Song and try to play a song that iTunes shows as 'Matched' the song doesn't play. Those that are marked as 'Uploaded' play fine. So far I haven't found *any* 'Matched' songs that will play.
