My roommate has an LG SmartTV and I logged my Netflix account into it when she bought it. Now that I'm likely relocating soon, I'd like to log the TV out of my account. I spent 20 minutes scouring the menus, the Netflix app, and Google, and can't find $#@!. There's no "Settings" button and nothing in the menus. Anyone done this? Is there a secret? Do I need to deactivate the device on the Netflix side of things?
