Nightfall Not Working

Since purchase, one of the things I've most been looking forward to is watching the Nightfall series that comes with the MCC. I was a bit disappointed when I found out the season wasn't all out, but onwards I went, eager to watch the first episode at least.

That is, until it told me to buy the blipping game. I downloaded the game digitally, so I failed to understand what was happening. I tried reinstalling the Halo Channel app, which is kinda wonky in many places to no avail. I searched for support online and found this thread with a growing list of other people who are having the same issue.

Are any of you guys running into this issue?
