Hi, I'm having a problem with spotify in my Galaxy S4 Mini...

I downloaded the app and signed for premium, picked my favorite songs, and toggled to "Available offline", but can't play the songs without a internet connection... The songs are already downloaded, I found even a folder from spotify in SD card with 1~2 GB, but when I try to play without a wi-fi, 3g or even in the "offline mode", the album covers vanishes and the music don't play...

I attached a screenshot to easily vizualize the problem... Notice that the songs have the green icon for already downloaded, but I can't play songs offline at all... And when I have internet connection, the musics plays normally...

Please, help me =( I love the app, and I want to be able to listen to my songs offline...

PS: Sorry 'bout bad english, I'm brazilian, and I can't find a solution in the brazilian site, and there's no such thing as spotify brazilian forum/community...

Thanks 😃
