Hello and psenet Hum, when you saved the tracks to offline did you make sure in the desktop app you selected high quality streaming? I believe this also selects the option so when you go to offline use for the playlists the desktop app will download them in the higher quality? If you forgot dont sweat it just select the slider button to take those playlist back to online mode and then go to Preferences in the desktop app and select the option for high quality streaming.
