Reactivated Premium, playlists don't sync on iPhone

[Baysaa]

I've re-activated, signed up for Premium again just now.

When my premium sub ran out first time all my songs got deleted from my iPhone. Now when I re-subbed to Premium, the Spotify iPhone app no longer syncs my playlists. 

When I'm connected to Wi-Fi, the app just says "0 of 149 tracks synced" next to a playlist I've made available offline. I don't know what to press to get it syncing!

Here's what I tried already:

Re-installed app

Re-logged in with Spotify details (after checking subscription status - Spotify Premium)

Re-logged in with Facebook details (after checking subscription status - Spotify Premium)

Playing the songs from the playlist made available offline, when the song finished playing usually that song is saved to my phone, but it doesn't in this case. I can still play the music through my phone, it just doesn't want to save/download them.

I have 7.0GB available on my phone.

So it randomly starts syncing now. I don't get it but I guess it's resolved now.
