I know that this is a stupid question:
But if you change the color of your Spartan uniform, (blue to a red, or red to a blue color in the Halo Reach game) how long will it take for it to update to Waypoint?
As my logo changed everywhere, but the uniform is still the same color…
It takes a while to update. It’s not as bad as on Bungie, which used to take months to update. Just be patient and it’ll eventually update.
For me, it has always updated pretty quickly. The most it’s ever taken is around half an hour or so.
Well, i certainly can’t tell, not precisely; It’s qutie random: Sometimes it takes weeks, days, and even minutes. I haven’t changed my Armor for a While, so i can’t tell you how fast does it update for me.
Mmh… Mine armor updates in about one-two days after a game.
well mine takes for EVER 
as someone said, its not as bad as bungie so yeah i would say for me a week at the longest
