When I open up my tv to access Roku all it does is show the word “Roku” with a purple glow behind it and a white circle below it. I’ve tried resetting the Roku and my WiFi router as well as unplugging it and it’ll come back and show the white circle under it sort of pulsing like it’s trying to connect to something and then will stop and stay frozen on that screen. Not sure what to do as I can’t even get to a screen about testing connections.
