I downloaded the Spotify Premium Free APK file and it worked great. Until I opened an app that force stopped Spotify while I was listening to music and when I went back on the app, all my downloaded music was not downloaded and I couldnt download it again despite being on wifi and allowing cellular data. So I uninstalled the app and deleted all files off my phone just so I can download it again from this same site, but this time when I try to download the music, a notification pops up telling me that its a spotify premium feature and asking me to subscribe to it.
How should I fix this??
