I know this has taken a while but we have a test build that supports these kinds of multiple genre tags now.
We’d like to make sure it solves the issue fully before rolling this out into a release.
I’m listing a few popular platforms below, if you want to test a specific platform that isn’t listed here please let me know and I’ll add it:
Linux (Debian):
https://artifacts.plex.tv/plex-media-server-experimental/1.31.2.6700-baa28a637/debian/plexmediaserver_1.31.2.6700-baa28a637_amd64.deb
Please give this build a test if you can and let me know if it’s working as expected.
