I have several playlists downloaded on my phone and laptop and then just one day they all disappeared on both devices. I already tried recovering my playlist from the option but my playlist still disappears after a few hours/days. I've tried the following troubleshooting to no avail:
Try a soft reset (reboot the device).
If that doesn’t help, try a clean reinstall. Be sure to locate and remove any Spotify folders or cached data from your device before reinstalling again.
If that doesn’t work, update your device’s firmware (if available).
If that doesn’t work, try using a different WiFi connection (please note that streaming dover mobile data might incur additional charges). If this works you probably need to restart your router.
If that doesn’t work, ask a friend or family member who also uses Spotify to log in to their account on your device. If everything works for them it’s likely the issue is with your account. If not, then it’s probably an issue with your device.
I've also tried changing my password but that didn't fix anything. I don't like using my data every time I use Spotify. I don't think that this is a device problem since both of my device has this problem. But I never had this problem when I was using my Samsung Galaxy Note 9. Hope someone can help me but this is really frustrating.
