Turning On Captions no Longer Works

I'm not the OP, but I have a similar problem.

With my Roku Streaming Stick, I could turn captions on and off with simple voice commands, "captions on" and "captions off". After I upgraded to a Roku Express 4K+, these commands no longer work. The system just takes me to a menu, where I have to click on further items to make the change.

This may seem like a small inconvenience, but as I turn captions on and off frequently, it adds up to a royal pain.

Captions are not just for the hearing impaired, who would likely leave them on all the time. They are also very useful for understanding dialog when the actors have thick accents, do not speak clearly, are covered by noise, or whatever. On the other hand, they are unnecessary and in the way for other programs, especially live programs where the automatic voice recognition is often wrong.

So the bottom line is that my streaming device upgrade was actually a downgrade in this respect. I paid more and got less, an inferior and poorly designed product that is less convenient to use. Is there any way to fix this, or do I have to return it?
