spartan ops trouble and specialization

I’ve completed the challenge of spartan ops where you have to beat all the episode 1 missions on legendary. I even got the achievement, but the challenge isn’t being unlocked. Why is that? Is it intentional, so it would unlock at the end of the week? Or is it just a bug.

Secondly, I bought halo 4 from gamestop and got a code to download the specializations early on. Ofcourse, i redeemed the code, but the specializations aren’t showing up on the specialization tab. Only operator and wetwork are showing up. And by the way, when do we even get to use these?

As the weeks go by more and more Episodes/Chapters of spec ops become availible. I think the challenge from today is for a Spec Ops mission for later. The challenges are probally generated randomly, after all there are achivements we cant even do till like 4 weeks from now : /

The specilizations were doing that for me as well for a small while. I redownloaded halo waypoint and loaded it up then back to halo 4 and that got my specializations back. Unfortuneately they are still locked untill you reach level SR-50 (thats rank 50 in the first specialization)

The all missons on legendary is a weekly challenge.

I bought the limited edition and im at rank 54 and the specialization are still lock.Anybody knows anything or why?
