Xbox App/Smartglass App

[suburbanl3g3nd]

Does anyone know why my "A" button on the Xbox app/Smartglass doesn't work? Every other button does except for that one and it's really annoying. It has been like this since my 1520 was on 8.1 and the most recent "slow" ring build of W10. I've tried uninstalling and reinstalling the app, disconnecting and reconnecting the app, and I don't know what else I could try right now.
