I spent the time to unlock all of the domain terminus videos for Halo 4 and could watch them when I first got them when the game came out. Now when. I reopen Halo Waypoint on Xbox and on PC. The videos are once again locked. I have seen another thread about this but it is a year old. I do have xbox gold membership, so that’s not the problem.
According to your Halo 4 Stats Summary, you’ve found 0/7 Terminals. You may have to go unlock them again.
We are currently investigating this issue.
