How do I force songs to sync to my iPhone

[jeremytondo]

I have a buch of songs I added to a playlist I have set up for offline listening. The issue is, when I add new songs to this playlist, they don't sync. Last time this happend I comepltely deleted the app and started from scrathch and they downloaded. I don't want to do that again. Is there a way to force a sunc?

Hey there, I have the same kind of problem here. Either the sync on my iPhone only happens like a few hours later after I added the song on my computer or, worse, they get added to the playlist but do not synchronise for offline listening. It's been like 3 or 4 days I added songs to one of my playlists, they show up correctly on both devices (Macbook Air + iPhone) but do not synchronise for offline listening on my iPhone, no matter what I do (of course I tried shutting and restarting the app). And this happens on my brand new iPhone 6S with 128 Go of storage, so it's not a storage-related issue.

Can anyone please give me some tips to sync my songs ?
Thanks !

Arthur.
