My Question or Issue

In my Spotify account I have designed that my music goes to my SD because I do not have enough space in my cellphone card.

Lately there are problems with my account. My music disappear and I have to download all my music again. And when I do it. My music goes to my cellphone and I have to send it to the SD AGAIN.

IT has been like this since I download the app foro the first time. I'd tried to re-install the app. And the problem continues. 

Please, help me.

Thanks in advance.
