My Question or Issue

I have been using Spotify as my primary music app for a long time now. Over the years I have downloaded a bunch of playlists - half of which I dont even remember.

I have now bought a new phone and setup my Spotify on that. However none of my downloaded music is automatically downloaded here, nor was a prompted to download. I am not sure if this is missing from the app or I dont know how to - but it seems to be a very basic functionality to be available.

Would really appreciate if someone could help. Thanks in advance 🙂
