Halo: The Master Chief Collection - Issue with Achievements

Hey there, I've been experiencing some trouble with getting a select number of achievements. The only ones I know of are for completing two levels, and the other one for collecting one of the plushy toys. I've played through one of the levels twice, and
while it acknowledges that I've played every level in the main menu, I still do not receive the achievement for either. On one of the same levels where I can't get the achievement for finishing it, I also don't seem to be able to get the achievement for picking
the Cortana toy Easter egg. I did, however, get an achievement for finding a different one, on the previous level, which was the other level I couldn't get an achievement for finishing. What gives?

:)

This is a persistent issue with Xbox One achievements. I completed Advanced Warfare on veteran yet the achievement took two days to unlock. I'd say wait it out and see what happens.

 

There's quite a few ( including myself ) that are having issues with Halo MCC achievements not popping up.

At this time I have 3 that haven't popped but one I earned 3 days ago finally popped today when I loaded the game so like Cthulhu mentioned above, just wait, it might take a few days but I'm sure they will unlock eventually.

 

I played first 10 levels of campaign with 15 achievements not unlocking after it say unlocked

- bad glitch needs to attention

 

Hirogen Hunter hey there

343 are aware of the issue. Usually they should come through within a day or two if they get jammed but on the whole, the problem is known and they are hopefully working to address it.
