Spotify on my iPhone works perfect on wifi but not at all on 3g/4g

Hello,

I  have a premium subscription, and i'm using spotify on my iphone (which is up to date).

My problem is the following:

- when i'm connected to a wifi network (i tried different ones), everything works fine (i can sync offline playlists, stram music, etc...)

- when i'm connected to a 3g/4g network, spotify can't connect to the internet at all (it actually says i'm offline). All the other apps that need a connection to work work fine, so i'm assuming the problem doesn't come from the phone.

- i tried a lot of your advices, but the problem remains the same: i can only use spotify on wifi, or to listen to offline playlists. i really can't stream any music (the "browse" tab even stays empty) on 3g/4g.

The problem has been the same for 3 months now (i didnt have spotify before).

Could you please help me with this? I find it a little annoying cause i'm paying for something i can't really use...

Thanks a lot in advance,

Max
