The only profile available to sign into on my LG OLED55B7A Plex App is not mine. I do not know the profile’s PIN to sign in. I do not know the admin PIN which is required to create a new user profile. I’m fairly sure the person who created the profile is someone whom I have no way to get into contact with. Their profile has a lock sign and a crown sign next to them.
I have tried deleting the app, unplugging the TV, waiting a minute, plugging the TV back in, and reinstalling + launching the app - but the user profile is still there.
The user with the crown is the actual account holder here. It sounds like you were a Managed User really. It wasn’t your account in this case. You should go to plex.tv and make a new account under your own email.
As far as why this is keeping the same account signed in when you uninstall and reinstall the Plex app, that is a problem. You might need to do a full factory reset on the TV to clear the app info if the uninstall is not doing it.
