SmartGlass Xbox controller buttons not working

So I figure there's a new Xbox setting I'm just not finding... But a couple of weeks ago (I think), the Xbox controller buttons (X, Y, A, B, Home, Menu, swiping to move the selection, etc.) in my SmartGlass apps (beta and release, Windows and Windows Phone) stopped working. I can still use SmartGlass for my A/V remote; just not an Xbox controller. What do I need to do to fix this? I've already tried uninstalling and reinstalling the apps on my phone, but I doubt that's the issue since it's not working from my PC, either.

Nvm. Unplugging the Xbox did it.
