Please Help

Hello guys,I have been playing about 15 MCC Matchmade games yesterday and under “Career” neither my Total Games Won nor both the total kills or total death numbers have changed despite winning all but one game. Furthermore, this also impacts my achievements. I haven’t made further progress with regards to the “play a total of 50 games” achievement and also didn’t receive gamescore for finishing Spartan Ops despite my friends getting them. This doesn’t just apply to one account but so far all of my accounts I tried. I have signed in an out of accounts, reset my build, uninstalled the game and installed it again and nothing has changed. Can anyone assist me with this? This also applies to Waypoint. None of the my games the past two days have registered on Waypoint

Best regard

PS. I have played a fair amount of games before without issues, hterefore this sudden change is very surprising
