This seems to be a bug when using custom theme.mp3 files when Plex has not yet provided a default theme song for the series.
- [Correct Behavior] Adding theme.mp3 to the root of a tv show that already has plex provided themes (e.g., pokemon) will work and be picked up without issue.
- [ISSUE} If you add a theme.mp3 to the root of a tv show that does NOT yet have a plex provided theme (e.g., dragon quest- the adventure of Dai) the theme.mp3 will not be picked up and used as expected.
Theme.mp3 music issue is tested and validated using Chrome web app and iOS plex app.
