When I am trying to filter for a song in a playlist, the song that plays is the first song in the playlist itself, not the filter. Say I filter for a song that is in the middle of the order of the playlist's songs and I click play on it, It will play the first song in the play list. If I filter for an artist and play the second song that shows up, it will play the second song in the playlist itself, unflitered.
This is on Android.
We can confirm this has been fixed in Spotify version 8.4.55!
If you're still having this issue, we'd recommend a quick reinstall.
Thanks for bearing with us,
