I have

1) Shaw cable,

2) Gateway (not Blue Curve) system,

3) Samsung Smart TV with a Harmony 665 Universal Remote.

I am unable to access Netflix. When I turn on the TV, I can see the Netflix app on the lower screen but nothing on my remote allows me to get to that app to open it. I have asked this question of Geek Squad who installed the system, Samsung and Logitech Harmony Remote. No one has a solution. I can't find anything on Shaw's website. 

Not currently able to get the Blue Curve system so please do not suggest it. I am trying to work with the systems I have.  

Please, please, please can someone provide a solution to this problem?
