We've got something a little different for you today. Lately you might have noticed that Spotify is not showing up in APK app stores in the United States. It turns out that there are some licensing agreement issues - causing the application to not be accessible in particular regions (in this case, the US). If you have the application already installed on your device or pay for the premium service, then you should be unaffected. The problem seems to be localized around having access to download the application from an app store like APKPure.com. Sometimes this can happen for various applications from time to time, and is not special to only Spotify.
If you're an avid OpenAPP Service user with your Astell&Kern music player, then this might cause some alarm. "What if this happens to other applications? Will I ever get locked out of my service?"
Don't worry. There is a workaround.
