I just got a replacement controller since my last controller died, and it's having connection issues. It's an Xbox Core Wireless Controller and it pairs via bluetooth just fine. Connects fine too. Until I launch a game, at which point the Xbox button starts slowly flashing like it's looking for a connection. It'll do this the entire time the game is running, and reconnects a few seconds after I close the game. Anyone know what the issue is and how to fix it?
