Apple Music "For You" Learning

Hi,

Does anyone know how the "For You" tab works. It's currently displaying, quite well really, all the artists/genres I picked in the initial set-up. I believe this is supposed to update based on the music you choose to 'love' within Apple Music. I have 'loved' quite a few different new albums (mostly Soundtracks as it didn't suggest many artists initially), but the "For You" tab hasn't changed from the original set-up genre/artists after 10 hours now.

Does anyone know if this refreshes periodically? Or whether the 'love' function is how it actually learns?
