I just signed up for the YouTube TV free trial. I was able to install the app successfully on two of my Rokus, but the 3rd (Roku 2 - 2720x) does not seem to have the app available for it. My first inclination was this device was not powerful enough to run the app. However, I can launch the channel using my iPhone to cast to the Roku 2. I was even able to register the device this way, and to continue to use it even after shutting my phone off.
In other words, the app appears to run fine on this device; except without having the app actually installed, I have no way to launch it except via my phone.
Am I missing something? Is there a way to get the Yiutube TV app on my Roku 2. (Please note this is NOT the YouTube app, it is the YouTube-TV app - i.e., live television).
