Welcome to the Roku Community.
We apologize for the inconvenience you are experiencing with your Roku remote. We understand that you have already tried resetting the remote, but the issue still persists. May we request the serial number of your Roku device so we help you further? If you are unable to access the Setting menu (Settings>System>About) to get this information, you can find the serial number at the bottom or back of your Roku device.
Keep us posted.
