I have the Roku Express+ and in the last few weeks, the live TV mostly does not work. After selecting 8 channel, I get the spinner and then the screen is black. I have checked for updates on both the app and the Roku and everything is up to date. I have removed and reinstalled the app, powered off and on the Roku and done a factory reset. And I have an excellent wireless signal. Does anyone know how to resolve this. It is unusable for live TV and it is on my primary television. Any help is appreciated.
