Coming from a TBolt where I would use Doubletwist to sync my music (even though the playlists were not synched on the Doubletwist app, they still synced in the default music player). With the DNA, Doubletwist does not even recognize my phone as being plugged in. How do you change the USB settings because I cannot find it anywhere (the USB settings from the drop down menu only gives options for mobile hotspot, internet connection mode, and bluetooth tethering). Also, tried using HTC Sync which synced my music but NOT the playlists. Did everything that the DNA User Guide said and still no luck. Any feedback is greatly appreciated!
