Smart Play lists empty with live update
Have several smart play lists that select songs based on when they were last played, i.e. include songs that have not been played within the last 24 hours. When I sync my iPhone or iPad, all the music and the play lists are copied to the devices. However, the playlists are now empty on the devices (full on my Mac). If Live Updating is unchecked the play lists are full. Playing the a few songs on these lists and then checking Live Updating does not fix the issue.
How can I get a smart playlist to use live updating and sync to iPhone or iPad?
