I shared my media library with another account. This now wants to create a second user. Unfortunately, my media library is not displayed there. The other account doesn’t have a Plex Pass. Create user worked.
Is that possible
I shared my media library with another account. that works well. He has now created a managed user. This user now has no permission to my media library.
If I also want to authorize this user, I can’t find him. Can I grant a managed user access to my media library or do I need an (in my case a third) account?
That’s correct. You cannot share media with managed users.
If this is a regular Plex account which is part of your friends Plex Home, you can share media with them too.
Edit: I’ve consolidated your posts / my response here; please don’t double-post things… that’ll only get confusing.
