New Apple Music transfer with SongShift, not adding ANY Spotify Liked Songs into my Liked/Favorites on Apple Music

Hey guys, after using the now integrated/default "Transfer music from other services" by SongShift transfer inside the settings app > apps > music....

I was not able to have my Liked Songs in Spotify added to my Favorited songs on Apple Music.

I almost exclusively listen to my liked songs, which means I can't quite use Apple Music yet. I have almost no playlists, so this transfer does not make Apple Music useful to me. Could it be that I did not transfer correctly? Is anyone else having this same issue? Has someone solved this?

Thank you so much in advance, looking forward to some help.
