Trying to activate private listening using the latest version of the Roku app for Android. My phone is a pixel 6. When I open the app and select remote, there is no headphone icon. I have my headphone connected to my mobile, and it's working.
The only thing I can think of is that my Roku device itself doesn't support this - though I don't understand why that would matter? My device is a Roku 3 model 4200x
