same song appear again in the same playlist

same song from the same album would appear multiple times in the same playlist, and this happened to many songs in my playlist

Hey there,

Thanks for reaching out!

Do the songs get multiplied in the playlist itself or the play queue? A screenshot of what you're describing would be of help!
Aside from this we can also try some troubleshooting - 

Let's see if removing the cached data of the app would make a difference. See the steps to do so here.

Hope this helps! We'll be on the lookout for your reply 🙂
