iTunes Syncing Issue

Morning All,

I seem to of only come across this problem since yesterday, updated my phone and no playlists were on my phone but my music libary was? Previously i've always updated my music by updated the playlist then simply syncing to my iPhone.

Now I can't find how to add new playlists to my iPhone and when I updated my playlist and sync to my phone, the new music is not showing?

Can someone help me with this please 😝

Thanks
