Apple Music Favourites mix not updating

I've seen this question has been asked a couple of times in the past, and I haven't seen a solution so far. Basically my Favourites mix hasn't been updated for about a month now, while the New music mix, the Get Up! mix and the Chill mix have been updating. How can I fix this issue? I have tried logging out and logging back in, turning off sync and turning it back on again, I have also tried uninstalling and reinstalling the app. What else can I do?
