Plex Server Sharing

[tom80H]

That’s kind of the expected behavior.
Tom has shared with _Belly, not with Bob and Joe.
Only the owner of a Plex Home can share (their) libraries with managed accounts. Other users can only share media to full Plex accounts.

Plex is not designed to forward shares.

There’s a feature suggestion discussing an option to share to an entire Plex Home or to let Plex Home admins forward media shared with them to their managed users.

Allow managed users to have access to shared content

I have a managed user for my child. I'd like to be able to allow that user to see specific shared libraries from my friends who have lots of kid appropriate content.   I don't see this as a problem since a managed user is really just a view into the primary users account and doesn't exist outside the home environment.
