How do I delete a friend when that friend made themselves Admin Home?

Unable to remove Home User

Your friend added you to his Plex Home (rather than simply sharing his library with you), and since you can only be in one Home, you essentially gave up your status. On the Users & Sharing page, click the X on your own user. The prompt should ask you if you are sure you want to “leave this home.”

Be aware that any managed users you had created were destroyed when you joined your friend’s Plex Home. You will have to recreate them.
