You probably need to sync the database first to have up to date data.

I write a python script to download some songs in the morning everyday, does this cause the database out date, then cause the sync problem?

Yes if you add songs in Navidrome and try to sync playlists too fast Symfonium does not yet have the updated Navidrome data.

You can force sync in the filter button before syncing the playlists.

OK, let me try it. Thanks.
