Problems with stats/service record after gamertag change

I figured the forum would be the best place to report this, so here goes. I recently changed my gamertag this week, and shortly after, Waypoint (on both console and website) wasn’t recognizing how I had my armor set up and apparently reports no stats whatsoever for Halo 2/3/ODST. This is really frustrating as I enjoy going through my stats on the older titles from time to time. Can this be fixed? Is it a known issue. Hopefully someone could help shed some light on this issue for me. Thank you much in advance!

I too have been having issues with Waypoint not showing my stats after a gamertag change… shows me as recruit and has no data for any game.
