I received a 9.3 update on the 12th ever since then my remote does not work for turning the volume up and down on my television. It will randomly work once about every 50 Presses of the button. In general however does not work at all I have tried to repair to my television I tried a different HDMI port nothing seems to help only started after this last update. The factory TV remote is so slow to respond we start using Exclusively the Roku remote and now it does not work. Any help would be appreciated
