On my android phone, I have about 1,300 songs saved. One day, spotify restarted my phone while I was listening to music and all my saved songs were gone, like someone went and manually unselected all my playlists' "download" button. This happened on my PC as well once or twice.
I've cleared the cache, reinstalled the app, factory reset the phone, and got a new account from the spotify support team and the problem persists.
Either let me know when this problem is fixed, or let me know when amazon music unlimited is coming to canada so I can migrate over because this is bull**bleep**.
