Hey there,

Thanks for reaching out!

Even if you get logged out of Spotify, your playlists and other library items should remain intact. 
With this in mind, I believe you may have logged in to a different account than the one you have previously been using 🙂 

This FAQ article should help you out with locating your account and accessing it. If you're struggling with locating the correct login credentials, take a look at this article as well.

Hope this helps! Keep us posted 🙌🏼
