I have installed spotify on my ipad air and if I try and download when connected to cellular network it either just hangs at 0/x tracks downloaded or if you try and stop / start any more downloads the app just crashes. On wifi it is fine. And yes the cellular connection works fine for anything else. I have uninstalled and reinstalled. Does anyone have the same issue or can anyone download tracks over cellular ok? I'm guessing by the version # 0.9 this is still beta?
