Playlists won't sync to my iPhone 5!
I've never had this issue before but every so often I like to manually sync my iPhone with iTunes on my MacBook. I created a load of new playlists on my iTunes because I find it easier to create playlists on a laptop but they won't sync to my iPhone.
The way I sync it is just with playlists so I have a smart playlist of all the checked songs (because I don't want my entire library on a 64 gig phone) and then I just check any additional playlists I want on it then sync and it's worked fine up until now.
All software is up to date, as is iTunes.
iPhone 5, iOS 7.0.3
