Not sure what happened today as I went for a jog. Opened up the Nike+ App and started itunes radio as I don't have a playlist set up yet. It was all good until the 1 mile mark where the music stopped playing. I paused the run and went into music and tried playing the music manually with no luck. So I went into my own music and thet didn't play either. I thought that maybe the earpods stopped working but as I continue to run I could hear the app telling you that you are at a certain mile. I also noticed my Signal was down to Zero on LTE which could have explained Itunes radio not playing. Anyways I continued running and about half a mile later the music came back on (not itunes radio). I finished the run and went home. Still zero signal so I restarted the phone and all its good again? Bug? Nike+App? Cold weather 40f?
