Spotify "undownloads" songs from time to time

I saved a lot of songs but sometimes they get "undownloaded" then I have to wait until all the song are "redownloaded". Why does this happen?

Hey @gigapies, welcome to the Spotify Community! 

You can try removing all of your offline devices here. Sometimes there can be a duplicate cache in the offline devices and it's fixed by removing them.

After that, just reinstall the app following these steps. Finally, you'll need to download the music again.

Let us know how it goes!
