Apple TV remote is scrolling erratically

I have an issue with my Siri Remote for few days...Indeed, I'm almost incapable to use it since when I try to use the touchpad, it's scrolling infinitely down. Left and right work fine, but selection button and touchpad control are unresponsive. To stop the scrolling I have to press the back button, but as soon as I'm pressing again the up or down button it's scrolling again. Since I have my Apple TV (almost 3 years) I had this infinite down scrolling issue, but it was not that often (once or twice a week) and it happened only on apps (Youtube mostly). I only had to close and reopen the app to solve it. I learned to live with it.. but right know it's impossible to use my remote and it's very annoying. I still can't find out if it's a software or a hardware issue. Anyone else had this issue and can help me to solve it?
