Hello,
I came across this closed topic:
It seems PLEX has disabled the ability to rename the “GUEST” account (not sure why, I think PLEX should re-enable this, this is MY server, I should be able to rename any and ALL of my accounts).
In the mean time, please rename my Guest account back to “Guest”.
PS: PLEX should also add the functionality to remove the User profile pictures or revert it back to the default picture.
Thanks.
