I have a TV with Roku built into it. It's not a separate device. When I was trying to open ESPN it would go black for one second, as though it was opening, and then immediately go back to the home screen. Now Prime is also doing it. I checked for updates and turned my TV off and on. I obviously can't just unplug the roku. I could maybe try to unplug the TV. I am wondering what other options I may have. Thanks!
