Doesnt work with previous loaded apps

This app is not user friendly. I have multiple network apps already on my phone but it doesnt recognize them. So when I find a episode of a show I want to watch it ask me to download the app.... I already have the app for the network show I want to watch. Example USA network already on my phone. I cant open the show I want and watch it on chromecast or Roku. So I open this app and type in USA network and the show I want to watch then it tells me to download the USA app..... that I already have. No sense! Just do away with this app.
