Can't find any players when matchmaking

I have Master Chief Collection for the Xbox One and starting yesterday, I was unable to be matched with any other players when in the matchmaking lobby. Let’s say I select to play a game mode online (Team Slayer, for example) and then I’ll sit in the lobby by myself for an infinite amount of time. I see a “search for players” and “players found” message on the lobby screen, but I am never matched with anyone.

The last time I played it and it worked was on Thursday, the 21st

Try hard reseting the game, once you do that, allow the “downloading latest matchmaking data” to stay on the screen as long as possible (few minutes). Once I let it do its thing for a while, I’m able to find games pretty easily.

Awesome
