Playback automatically pauses on iPhone 6

I commute to work each day and pass through many different service areas. Sometimes I am on LTE, sometimes it drops to 3G, and there is two spots where I don't have service. Which is all fine and dandy and has never been an issue when I was streaming from Spotify. However, since testing on Apple Music, I have noticed that when I go through any of these areas where my connection changes, Apple Music pauses. I have to hit play to resume playback. My music is all offline, so I am not streaming. I have even done additional testing with Apple Music playing, I switch my phone to airplane mode, music continues to stream, but when I turn it back on and it picks up a signal, it pauses the music again.

Has anyone had similar issues or a fix for this issue?

Thanks!
