Hi jlattal,
Thanks for the update!
When using a simple remote control, you don't need to pair it with your device because it runs on IR; all you need to do is point it directly at the device without any interference. On the other hand, Roku voice remotes require pairing with the device.
Try this out and see if it helps you. If your Roku streaming device is acting up, try unplugging it and giving it a break for ten to fifteen minutes before connecting it back in. In addition, attempt to take the batteries out of your remote (and if at all possible, put in a fresh set). Then give it another shot and see if the problem persists.
If it doesn't work, please post back here with your device's serial number, and we'll take it from there.
Best regards,
Rey
