Basically, I'm having problems getting the box to appear when replying to messages, which allows me to physically type instead of using the onscreen keyboard with my XBOX One controller. After doing some quick testing, for me, it seems like the box does not come up when my XBOX One is set to Instant On. When it's set to Energy Saving Mode, the streaming app works correctly, thus when replying to messages, the box appears in the XBOX app stream, allowing me to use my keyboard to type replies.

With Instant On set on my XBOX One, am I not able to type message replies via Windows 10's XBOX app?
