127.0.0.1 is a special network address which works to reference the local host no matter what network it is attached to. Playlists were being set up with the IP address on my home network which was different on hotspot mode. Manually editing them to 127.0.0.1 made them work even in airplane mode from QuickPlay. If they are playing back on the same device loading the playlist it will be fine. Otherwise if you interpret the file on glider then rewrite the address to the current address for Poly.
