Custom Challenges updating?

Hey guys, I made a custom challenge set for 800 kills in Matchmaking firefight. and I played a game, and it’s been 10 min since the game and my kills aren’t counting? The Custom Challenges usually update right away, I always check right after games to see where i’m at in the challenge and they’ve always been up to date, but it doesn’t seem like it now. Am I doing anything wrong? Or are they not working right now.
I’m also playing in the Firefight matchmaking, not score attack.

IDK but mine is not working either. I can place the challenge but the kills don’t update after I end the game. I really wish it would though…
