After discussing with one of our colleagues who's in charge of the hardware issue, I was shocked to realize that for the Infrared signal distance. I know that when using an infrared device, you need to maintain a certain distance to use it. And all infrared devices have this disadvantage that you need to keep Line-of-sight to control it. It causes so much inconvenience when you use it. But you can add an IR Repeater to boost the signal so that you can use it smoothly. https://www.amazon.com/USB-IR-Repeater-Infrared-Extender/dp/B08CBJVPQJ/ref=sr_1_5?crid=3D7X60RSA8TCZ&dchild=1&keywords=ir+repeater&qid=1613304558&sprefix=ir+%2Caps%2C415&sr=8-5 You can buy this link, and then take a screenshot of the Payment & Paypal Account. I will pay you all the costs. Good news for you,X1 will release in the next few months. X1will support PS3、PS4、IR Signal Boost、point anywhere remote、both connect 2 Bluetooth at once. X1 will solve this problem And dear, don't forget to copy the Order Number within your next email so that I could arrange the resolution for you asap.
