So I deleted a user from my "Friends" via the PMS settings -> Users over 30 days ago. But today he was able to watch content from my PMS from an external IP! I checked the following: https://plex.tv/api/users/?X-Plex-Token=TOKEN and his username or email was nowhere to be listed.
How is this possible?
