I Have Spotify Premium and on my Mobile everything works perfectly. But on my Desktop any Song (even those which I have downloaded in offline Playlists) just wont play. Tose songs i didn't download are just "not available (theres appears a blue notification at the top of the page) and those in playlist just skip too the next one and next one and next one... -> it does not work.
I've already deinstalled the App and reinstalled it (win10) - still not working.
I'd appreciate your help via personal message.
