I changed my gamertag on xbox a few days ago and now on halo waypoint it says that i have never played any of the halos like 2, 3 odst and reach when i have, has it just not updated yet or is there something i need to do to make it recognise it again.
Help please
You might need to play one or two MM games in Reach.
But what about my halo 2 information i cant play that online anymore?

I would of thought it just takes time for your profile to update. No big deal 
Waypoint tends to take a while to update after a gamertag change, I’ve changed mine once and it was a few days before my Halo 2 stats showed back up.
Play at least 10 games of anything even if its 10 5 second custom games.
It will then take a few mins for the games to register and then you should have a record.
My recommendation: Play some more Halo games to pass the time.
