XB1 Smartglass app was worked on all my devices (Win8 Phone, Win 8.1, and Nexus 7 Tab), but this morning my remote buttons wont work within Smartglass. Smartglass will launch my apps, and adjust my volume, but none of the emulated remote buttons work i.e A, B,X, Y Home, etc. Not sure what has happened. It's connected to my XB1, I can launch apps, see achievements, etc, only the remote doesn't work anymore.
Any clue as to why this would happen?
