“Sharing” a media title
and “granting access” to media (if it’s stored on your own Plex server)
are two different things now.
Sharing is for notifying your friends about a track, album, artist, movie etc.
e.g. “this album is awesome!”, or maybe “this episode blows”

“Granting access” makes media available for streaming from your server.
