Loving the Watch 4 so far.I have LTE on mine. My only issue is with Apple Music and Apple Radio. They simply do not seem to play when I go for a run. Apple radio will just show a song and then not play it and basically act like there is no music to play. Apple music will load a playlist and then on it's own, scroll through every song on the playlist, but not play anything. It will play some songs in my library and that is it. I notice this happens more when I use an app like runkeeper or apple's exercise app. When I go cycling, I dont use any apps, and the music streams a little more reliably. What is the process to say - add a playlist using Apple Music on your phone and then put in airpods, leave the phone behind, switch to the watch and pull up that playlist? Because just getting a new playlist to show on my phone can be a real pain. Does everything have to be in the library to work? That doesn't make much sense since I have LTE. Maybe am doing something wrong.I just restarted both devices and am going for a walk to see if anything changes.
