Mood tag added by MusicBrainz Picard ignored by Plex server

Server Version#: 1.22.1.4275
Player Version#: 4.53.0

I’ve created a library from scratch with “Prefer local metadata” and Genre set to “Embedded tags” after updatng Gnre & Mood tags using MusicBranz Picard. The Genre was picked up but not the “mood” tag. Does the tag need a different name?

Thanks

I’m pretty sure Plex will not take moods from embedded tags. They only come from online sources.
