Support: Changed GT, missing Reach stats

Hello, wondering if someone has experienced this problem and helped. I changed my GT (about 2 weeks ago now) and my Reach stats won’t load in Waypoint. They load on this site, every other site, and in Reach itself, but for some reason the Xbox dashboard app (Waypoint) says I’ve never even played Reach. It also says I’m “missing achievements” but my achievements are there. Any idea what could have caused this?

I tried searching, but there’s WAY too many topics in these forums lol.

Thanks in advance!

When was the last time you played a game on Halo: Reach?
