My device serial number is X004008EX2UY. I was using it, one minute the remote was working and then the next it didn’t. I tried all the trouble shooting steps listed on your site. Nothing worked. This included trying multiple sets of different batteries. We have a roku in another room, so I took that remote and tried it on the roku in our living room. It worked fine. I took the batteries out of that remote and tried them in the one that wasn’t working, and it still didn’t work. Finally I tried using the remote directly in front of the receiver, and it will work directly in front of it, up to 2” away. Then it does not work. Really inconvenient when you are trying to sit on the couch and select shows. I was wondering if a replacement remote could be sent, as this is only 2 months old. It was purchased on Nov 24, 2022 from Amazon.ca. Our old roku that is in another room is about 4 years old and still works. So thinking this new remote might have been faulty from the get go. Thanks you.
