Recently Changed Gamertag, Stat's wont show?

Games Other Halo
1

I Recently changed my Gamertag From MangekyoScopez to PrometheanTitan, I have logged onto Waypoint via xbox and reach and other halo games to see if my stats would carry over to my new name as they did in BF3, Alas I have had no success is there another method I could go about to transfer them Or Does it take a certain period of time?

Help Would be Most appreciated.

Let me Correct that, my base Statistics such as KD Will show If I take a Certain Route But as Far as just clicking on my name and Going to Stat’s Or Service record I come to a “Authentication Required” Screen, https://www.halowaypoint.com/en-us/Career/HaloReach/ServiceRecord?gamertag=PrometheanTitan Saying my tag is invalid?
