Cant even connect

Wont let my phone connect with my receiver. Then once is connected is always buffering. Then once all that is done the app acts up. Wont connect with my receiver through my phone. Wont let me see my channels the ones I have order in my package. Dont want to see other channels not relevant to me. My channels keep acting up any where I am example my work the car or on the road with my kids this app is supposed to be an experience but is more of a headache
