Apple Tv not working on my iphone 11

I bought an iPhone 11 and was promised an 1 year free subscription to apple TV but the feature is missing from my apple tv iphone app. When i try to log in on apple tv plus on my browser with my apple it keeps reseting and asking me to connect again and again.... What's wrong?

How can i access Apple Tv from iphone 11 or Macbook Pro Retina late 2013?
