My Roku Express times out after inactivity. I've looked in Settings to try to extend the inactivity time constraint, but with no success. I have a unique reason for this, I live with an elderly parent who cannot operate the system, and I need to be able to leave his preferred subscription channel on for a longer time when I'm not available to work the system for him. Can anyone help? Is there a way to extend that inactive time before it goes back to the home screen?
