I recently boarded a flight and prepared to listen to offline music - only to find that all of my offline music from dozens of artists had been removed from my phone.
What is going on here? I saw some other posts stating that the OS could delete songs if there was insufficient space, but I have plenty of extra space (>20GB) available.
Very frustrating that I need to go back and manually add all of this, without knowing whether or not it will happen again.
I've already re-installed the app once before for offline playback issues, please don't recommend reinstallation as this isn't really a troubleshooting step.
Phone is a OnePlus X, Spotify version 126.96.36.1992 armV7
