Ratings from Apple Music

I know you can’t set the ratings for a song in Marvis itself because it doesn’t sync to Apple Music, but Marvis can read and display ratings from Apple Music. But when I tried to make a playlist with rules based on ratings, it doesn’t work at all in Marvis. For example, I have a smart playlist in Apple Music for songs that haven’t been rated, and on Marvis that playlist is just empty. If I make a playlist in Marvis with rules about ratings, it doesn’t work either… am I missing something?
