I am the home admin with Plex Pass. I have created a playlist that I want to share with my a managed account of a user in my household/same server. I have clicked share playlist and selected the managed account of who I want to share the playlist with. The shared playlist does not show at all for the managed account. Yes, the movies in the playlist are within the content guidelines I have set on the managed account. Yes, we have tried iOS, Web App, and Android TV; it does not show.
Where did you look for this playlist? I messed around with a shared music playlist ages ago, and I seem to recall it appeared in a new menu item “Shared Playlists”, rather than the default “Playlists” item.
I could be wrong, but I just want to be sure you checked all over on the managed user for a new menu. Possibly use the search bar and enter the name of the playlist, it might show up.
