I have my local files set to be read. All my titles work fine except for certain Disney movies with local extras. Any reason why? Is there a number cap on extras that can be available?
Plex Media Server version & platform?
Available at https://app.plex.tv/desktop/#!/settings/devices/pms
After adding the extras, did you refresh the metadata for the movie?
Please show naming & organization for the movies and extras (directory listing, etc).
