Long press mute function still DISABLED!

I reported a bug here:
Software bug in version 15.0.4 build 5531 | Roku Community
The bug is a function that has worked for a long time - when you press the mute button on the roku remote the player would cause the display to go black, but would leave the audio running. That feature has been disabled when a player updates from software version 14.6.4 build 9915 to software version 15.0.4 build 5531. Since then another update has occurred to build 5534, but the function remains disabled. And there is no way to prevent updates. I have had three Roku devices suffer this function being disabled and it appears Roku does not care that their updates are breaking a feature! I used this daily to bring up YouTube videos with long musical audio tracks and kept the audio running while the video was turned off.
