I'm having this pretty annoying issue for almost a month now on my Spotify app (my Android version is 5.1). I like to store my offline songs inside a playlist, since this method keeps all my downloaded songs together and organized and helps me to control its size as well (storage concerns, right?).

Obviously, I used to sort them using the ''Recently Added'' option, which organizes songs from newest to oldest. However, everytime I activate this option, it completely scrambles the order of songs inside albums for no apparent reason (I always add whole albums instead of seperate songs), putting them in alphabetical order instead of following their specific track number. I can't find a way to fix that and it's getting on my  nerves, since it's never happened before. My app updates all the time, but this problem doesn't seem to be the focus or maybe I'm the only who noticed it.

When I use the same option in my Windows 10 app, with the exact same playlist,  songs are in their respective track order as they should be and only the albums themselves are changed. I'm just confused.

Can anyone explain what's happening?
