I had this problem on our Samsung TV where no matter what, I couldn’t log into the Netflix app. I noticed that it happened just after I had changed the password to Netflix. Now lets not think about how fucking difficult it is to type in an email address and secure password using just a remote, but then the frustration of doing it over and over again and being told the login is incorrect… I was close to smashing the TV with the remote and then throwing the whole lot out the window.
Anyway, after I finally accepted that it wasn’t me but it was either the TV or the Netflix app, I started googling around. Turns out there is a secret way to reset the Netflix app. Once I did that I was able to log in first time. WTF Samsung and Netflix? how can this bug exist?
Anyway the magic is:
Start SmartHub and select the Netflix App, then on the TV remote, press the following sequence:
Up, Up, Down, Down, Left, Right, Left, Right, Up, Up, Up, Up.
Once you have done that, the app will ask you if you want to Start Over. Hit Yes, and you should be good to go.
