ok so i changed my gamertag like a month ago already, i just played a halo reach matchmaking game for the stats to show again but stills the same 
and yes, i’m playing the 360 version
can someone help me, please?
you have to either look up your old gamertag, or if you have a hashtag in your xbox name, you have to type in everything, but if you didn’t hear already, h343 is shutting down the xbox 36- servers so maybe that’s why you can’t see your stats
