I have had roku express for a few years now, and recently I have subscribed in Amazon Prime videos, I went to add the Amazon video app from my roku but it is not available, I went to the website and found Amazon prime when I tried to add it it appears as grey button (can't be clicked) I tried to install apple tv just to see if it works from the website, and it works, but amazon prime does not.
On my amazon prime account I tried to add devices, anyways it is asking me to give them the code that appears on my tv, but my tv does not have amazon prime.
What is the solution? I think it is some licensing issue. They need to solve it. I have already faced a similar problem with (Starsplay) ROKU sorry to say that but you ain't good enough.
