I am a Premium user, and in the past have been able to sync my music on local files on my computer to my iPhone. Yet, I began having issues about a month ago, so I reinstalled the applications on my iPhone, iPad, and Computer. Yet, I am still not able to sync my music from my computer to my devices. I have tried using 3 different wi-fis and tried creating a computer-to-computer network on my Mac, but have had absolutely no success. What steps can I take to sync my music from my computer to these devices? I am getting very frustrated with the spotifuggle app and do not know what I can do to ameliorate this problem.
