We can see that you're working to resolve issues with your Roku TV remote, and we truly appreciate the troubleshooting steps you've already taken.
 
Have you attempted to reset your remote? We suggest changing the batteries and trying to reset your Roku remote by pressing and holding the Back and Home buttons simultaneously for about 20 seconds. After doing so, pair it again to see if this makes any difference.
 

We would recommend trying to see if that resolves your issue. Please keep us posted.

Thanks,
