My plex server wont allow me to add my family members to my plex server to switch between accounts on tv, tablet or even NAS webpage, im a plex pass member and according to plex support pages on the subject you go into settings + plex home to add users, but i get nothing where i can add users in plex home section like support webpage suggests except to only change PIN or remove it.
Do you already have users added to your home? – there’s a maximum of 15 members for a Plex Home, that includes the admin.
Does your own account have the crown / home admin indicator as listed above?
