Hi, @jgraver!
Thanks for posting in the Roku Community!
We acknowledge that you have recently reached out to us regarding the Guest Mode feature and its ability to be controlled on all devices at once. We regret to inform you that at present, this option is not available.
Ensuring our customers have an excellent streaming experience is our top priority. Thank you for your feedback which we will forward to our Roku team for review.
Feel free to let us know if you have any other concerns. We are always here to listen and take action.
Thanks,
