I figured it out. Previously had Feishin connected to Navidrome through Subsonic API. Once I changed that connection to Navidrome API, the smart playlist option appeared.

I only have the Public toggle, the Smart Playlist toggle isn’t there for me. Using Feishin 1.13.0

I don’t see an option in either Feishin or Navidrome for smart playlists. Where/how are you creating these playlists?

How do you create a custom station?
