Same here. Just installed plex and when I try to access for the first time, I enter my gmail credentials (I use them to access Plex.tv), and then the screen shows “NOT AUTHORIZED” “You do not have access to this server”.
Should I access just using email?
Does the app communicates with Plex.tv in order to retrieve and validate my login credentials?
Is there a workaround for this issue by editing some file of the app at /home/umbrel/umbrel/app-data/plex?
