I can see the guide. And use the remote but cannot see where you click to actually watch live on my phone?
I am on iPhone 5s on iOS 9 if that helps, thanks.
I have an Android phone but, I guess, the sequence will be the same.
Click on a program in the Guide then press Watch Now and then press Watch on Phone.
At the last stage you should see two options - the second is Watch on TV.
If you only see Watch on TV then you are trying to watch a channel which cannot be streamed. Not all channels can be streamed; only those with the little wifi symbol.
Try channel 104.
