I have used Roku for years. I recently canceled AT&T Now and subscribed to Sling. I added the icon on my main room tv and logged in - it works perfectly. However, in my bedroom now when I turn on my tv it will not even go to my Roku main page and the Roku remote does nothing. All I see is the sling symbol on the screen but can’t even login to it - frustrated!! How do I get Roku to work now and enjoy sling and all of my other subscriptions? Please help.
