They had Spotify apps, the two most popular were lyrics apps. Then they removed the apps and added lyrics inside Spotify, and now there is no more lyrics at all.
Obviously that's a very demanded feature so they must have a strong reason not to have it anymore (legal issues probably).
I personally used it all the times for improvised karaokes so I'm very upset to not have lyrics on demand anymore.
I can't make it appear on my app (iOS) and the help link [1] shows that's it's enabling comments from Genius about the lyrics, so not the actual lyrics synced.
