With the dispute between Roku and Google over the YouTube TV app, what do you do if you don't already have the YouTube TV app installed? Are you out of luck?
No, not really. You can still watch YouTube TV on Roku without the YouTube TV app. You do it through the YouTube app.
Scroll down to the bottom of the menu on the left and select the YouTube TV item.
Go to YouTube TV. It will load.
Then the splash screen.
And there it is. To sign in, click Sign In.
Congratulations. You're now watching YouTube TV through the YouTube app on your Roku device.
