Cannot donwnload the music

[thiasoraya]

Hii,, I use Spotify using my device OPPO F1s, I already registered into a premium. But the download menu doesn't work even though I have checked the menu "download using celular" But the songs cannot be downloaded and cannot be listened offline. I have to go online if I want to play the music. My space is ready ag 6 gb

Please if anyone can kindly help me with this trouble?

Thank you very much

Regards,
