We have been having a similar problem with our Samsung Smart TV on and off for months, and it just started happening almost every time we login into the app now. We get a message that reads:
"It looks like Netflix has been deactivated on this device. It could be an issue with your account, or perhaps your device was deactivated on Netflix.com."
It's getting to the point where I am going to change the Netflix password to something ridiculously simple to type in on the remote. This has been going on for almost a year now!
