Sdcard function doesn't work

[camereye]

Hi,

I am fed up with the premium option. I travel a lot and I need to sync my playlists on my sdcard. It seems to work, but after a few days, Spotify change automatically the option from Sdcard to internal storage. So I loose all my sync music. I have this problem for 2 years now with 2 different phones, I am actually in a train with no music because of this problem (I synced again everything yesterday and lost it today). I am definitely tired of this (and the fact that Spotify is the only one streaming platform that doesn't allow an album view in the playlists), and I plan to stop my subscription to test google music or something else.
