My girlfriend and I have both been having issues with internet connection. We are both on desperate phone plans. I have AT&T and she has Sprint. Samsung Galaxy S6 and S7. The app will work perfectly fine and then as soon as we turn it off and close the app and try to play a song there is no connection unless we restart our phones. Sometimes that works and sometimes we just give up and it works later. We have even been connected to Wi-Fi and still weren't able to play anything that isn't downloaded.
