Hi EPopeney,
Welcome to the Roku Community.
We appreciate you letting us know about the issue you are experiencing and the detailed information you have provided. We'll help you resolves the issue on your Roku devices. Have you tried to remove the batteries from the Roku remote and see if there's any difference? Perhaps, the TV is accidentally opened with the Roku mobile app while trying to use a different app?
Lastly, it was reported performing a system restart resolves the issue. Have you tried to restart your Roku devices? We would recommend doing this from the Settings menu by navigating to Settings > System > Power (If you do not see a Power submenu, skip to the next step.) > System restart.
Thank you for your cooperation. Keep us posted on how it goes.
Regards,
Nimfa
