Wow, first time I have been censured on this discussion groups. My post has been just vanished.
Just because I have used the word stupid on it? Totally unjust.
Anyway, I came back to report that I has slammed Apple on this one maybe too soon, but what is it with your cryptical error messages that have the ability to really enrage your customers without really explaining what is happening backstage?
Well, here is what has happened to me, I hope this helps others with the same problem:
I transferred 1GB of music tracks from an audio guide I just bought to my next trip to Rome. The DVD came with 92 common MP3 128kbps non protected tracks, nothing fancy here. I dragged all the tracks into iTunes on the MBP and was shocked after seeing the infamous "Some of the files were not copied to the iPhone “name of iPhone” because iCloud Music Library is enabled on this iPhone." message when trying to manually drag them to my iPhone 6 plus,
I am testing the Apple Music service at the moment and was really ****** off because I have never had this problem transferring tracks to my iPhone before. I then rushed into the iTunes feedback page and voiced my complain to Apple.
What followed has really blow me out of the water:
My upload internet connection is channel is really lackluster, 1mbps. Can you guess my surprise when I found that after just MINUTES the hole playlist showed on my iPhone under the My Music tab? I could then play all the tracks of the audio guide from there. I could not believe my eyes so I proceeded to activate fly mode on the iPhone and as expected all the songs disappeared. After this I decided to go online again with the iPhone and mark the playlist as Make Available Offline. All the playlist's tracks were downloaded in minutes to the iPhone and now sit there to be played whenever I want.
I think the Music app has transferred the tracks automatically using my local network, or maybe Apple has found a way to secretly break the laws of physics, I really don't know. I have to say that I DO NOT have enabled the Share My Library on the Local Network tab on iTunes preferences.
I have no idea how they did it but the tracks have been transferred, so if you see the same error message just let the Mac stay on and wait some minutes to see if the songs appear in your phone.
