I’m from russia and i use a jellyfin media server witth russian language settings for russian-speaking users.
But, I have problems with russian metadates from TVDB.
“Fear the Walking Dead”, on the TVDB is available metadates in Russian for all episodes, but jellyfin loads metadates in English
“Breaking Bad”, on the TVDB is available metadates in Russian for all episodes, jellyfin correctly loads metadates in Russian for 4/5 seasons, but for 5th season in English.
But some TV shows works correct. “Game of Thrones”, “Love, Death and Robots”, “House M.D.” have no problems, jellyfin can loads metadates in Russian for all episodes.
I need your help and sorry for my English)
