Server Version#: 1.24.1.4931
Player Version#: Current web or iOS
I’m using the plex server on an Nvidia Shield.
Lyrics don’t seem to be present - checked a number of popular songs from a variety of albums and artists. I don’t see any settings in plex server setup that even mention lyrics. Seems like it should be automatic from what I’m reading but they don’t show.
There is no setting you may have to refresh metadata on music library to get the LyricFind ones if you recently got a Plex Pass. However they are not available in all countries, all supported countries are in list on this page https://support.plex.tv/articles/215238778-automatic-lyrics-from-lyricfind/
during playback on web there is a Lyrics button on the bottom right of the on screen controller. On iOS click the ... during playback to see the option to show lyrics.
