Titanfall Xbox One In-Game Chat Not Working

Has anyone else encountered this problem? My microphone works fine in party chats, and other in-game chats, however, in Titanfall I can only hear other people. It acts as if my mic is muted, and won't pick up my voice.

I've also noticed that nobody really talks much, so I was wondering if they are having the same issues, or they're just quiet/in their own party chat?
