I am trying to sync new songs/playlists from Amazon Music but once the sync starts it stalls. The sync got to 4% complete and at the same time drained 10% of my battery. I have uninstalled and reinstalled the app to my watch, tried several different sync options, checked the wi-fi connection, plugged it in to charge, and set it right next to the router. Now it won't get past 0% complete. Any ideas?
