Hi, I am experiencing some sync problem between my iDevices. For example, I have downloaded "Intro To Yo-Yo Ma" and can see the playlist under "Apple Music Playlist" on my MBP. However, even though there is a "Intro To Yo-Yo Ma" playlist on my iPhone 6 Plus, there aren't any songs. It's an empty playlist: An other problem is "Add to My Music"; when I use it on my iTunes (MBPr), I can go "My Music" and see the song/album. However, nothing is added to my iPhone's "My Music". Even if, I use "Add to My Music" through my iPhone's "For You", "New", "Radio" and "Connect", can't see any songs/albums on iPhone's or MBPr's "My Music" tab. These are not very frustrating, if you use a Mac and iPhone, but I use the music app on 2 iPhones, 2 Macs and an iPad. Trying sync (by sync I mean searching songs/albums and adding them one by one) all songs can be huge problem. Does anyone experiencing same/similar problems like mine? Also, does anyone know how to solve it? Thanks!
