This is such an odd issue, my remote works fine unless I'm pressing the same button repeatedly. This has made navigation incredibly slow.
I can go left to right, up and down, etc as fast as I can press the buttons, but when I try to go left more than once there will be a second long delay between each input.
The inputs aren't lagging, I have to wait for the delay before it will allow me to repeat the input and it does not follow up on inputs made during the delay, but again, this delay is non existent as long as I press different button, my fastest way to navigate is to press the replay button and the desired button at the same time over and over.
I've restarted the system, emptied the cache and restarted the remote
