i got the message i made it to the finals in tier 1 but when i search my gamertag it dose not show up 
Glitch…don’t worry same thing happened to me. Just wait til the next update then it will probably show up.
I figured out that the Infinity Challenge finals leaderboards search function is case sensitive now. Enter your gamertag exactly the same way as you see it on XBL and you should see your ranking displayed in the applicable tier.
ive tried it dosent show me on the spartan ops or multiplayer does this mean all this time ive spent playing multiplayer and sparten ops is gone ??
its shows up now
