Can’t get nightfall armor.

I got my Xbox with the MCC and Halo:5 and put the codes all in. But when I went to the halo channel to get the nightfall armor It would not let me so I went to the store to look at it and it said I owned it and had it installed. Should I reset/restart my Xbox to fix this problem?

Hey, OP, I don’t know if this issue has resolved itself yet, but have you tried uninstalling the Halo Channel app and reinstalling it?
