Spotify Generated Playlists

My Question or Issue

I noticed I used to be able to choose artists (most likely on my phone) and the selection of artists would be used to generate music from them as well as similar artists. In my playlists section, it reads: "Your Dinah Washington and Billie Holiday Mix". It would read By: Spotify as well in the appropriate section. 

I don't know where this feature went but it disappeared long ago. However, it recently showed up today, on my app on my phone, where it replaced the Good Evening Section on the homepage. I added my artists but the playlist never materialized and the feature has yet to come back.

Any advice?
