Error when removing and re-adding songs to a playlist

[Tilin24]

Describe the bug When I remove a song from a playlist, it stops appearing in the playlist, as it should. But then, if I try to add the song back to the playlist, I realize I can't because when I select which playlist I want to save it to, it appears as if the song is still in the playlist, which it isn't. I've tried exiting the app, closing all background tasks, reinstalling the app, and importing my playlists from the backup file, but nothing has worked. Then I decided to sync the playlist with YT Music. It turns out that the song does appear in the playlist in YT Music, but not in the app. And if I try to update the playlist from YT Music, it simply won't update, not even if I add new songs to the playlist in YT Music. The only solution I've found is to create a new playlist and move all my songs to the new playlist, but it's quite annoying having to manually move all the songs to a new playlist just because one song has a bug.

To Reproduce Steps to reproduce the behavior:

1. Make a playlist
2. Add a song to the playlist
3. Remove the song from the playlist
4. Try to add the song again to the playlist

Expected behavior When I delete a song I hope that if I want to add it again it doesn't appear as if I never deleted it in the first place.

Screenshots

I deleted the song from my playlist, but when I try to re-save it, it appears to be in my playlist

But when I search it on the playlist I can't find it anywhere

But when I look for the playlist in yt music, it appears to be there

also before that can you try clearing app data?

Closed, due to no reply and unable to recreate.
Please reply if not solved on latest (v0.2.21).
