Noticed this yesterday but lyrics are no longer working in YouTube Music (although they seem to work fine on Spotify). Lyrics button is not showing and pressing L does not work either.
Tried installing it on the Edge Add-ons store with no luck and refreshing does not seem to fix the issue either.
Also tried on Chrome and Firefox with the same result.
