Since my original post all 4 Roku Remotes have the same problem - al purchased at the same time with the same software update. It works one minute and the next stops working and then later starts working again. For us, it is ALL TV function controls and SOund Bar controls - on/off, volume and mute functions. Never know when it might work so always have to keep the original TV remote handy which always works fine.
I purchased Philips Universal remotes as a result of your defective remotes until Roku figures out a fix, but that option eliminates the voice function and earphone function.
Would really appreciate it if Roku could work on this problem. Pretty obvious it is not just me and not an IR positioning problem. Thanks.
