Netflix officially discontinued support for the Xbox 360 in 2017. So, you won't be able to stream Netflix directly on your Xbox 360 anymore.
However, you still have options for watching Netflix on your TV:
* Use a different streaming device: You can connect a newer streaming device like a Roku, Amazon Fire Stick, or Chromecast to your TV and stream Netflix through that.
* Use a Smart TV: If your TV is a Smart TV, it likely has Netflix built-in.
* Use a gaming console: The Xbox One and Xbox Series X/S both offer Netflix streaming.
I hope this helps!
