Could you tell us more about the issue you're experiencing? Have you tried the suggestions posted by @RokuDanny-R in this post? If yes and the issue persists, reply here with the serial number of your Roku device associated with the affected remote. This can be found at the back or underneath the player itself.
We'll keep an eye out for your response.
