Can't watch Nightfall. Help?

I want the Nightfall armor for Halo 5, and I need to watch the Nightfall series. I remember I had problems back when MCC released, I entered my nightfall code and still it was saying that I need to “Buy Halo”. I remember I got it to work at some point because I have seen 1 or 2 episodes.

Now, a year later, this issue is still not yoink* fixed??? I tried searching but I found no answers.

Someone knows how to fix this?

Well, Ive spent another hour reading through posts from every corner of the internet and waypoint and 343 hasnt solved any that i can see. So 343 can go ****. A YEAAAAAARRRRRRRR!!! STILL NOT FIXED!!!

It makes me mad that this crap is still not fixed. I’m still trying to find a fix to this problem.
