When was the first time you noticed achievements werent unlocking for you mine was the truth and reconciliation close quarters combat achievement. I dropped the sniper loaded a new area of the level came back picked it back up and ever since then achievements no longer unlock. also i got the bite the hand achievement even though i havent played multiplayer
I played first level of campaign with 15 achievements not unlocking after it say unlocked
bad glitch needs to attention
I noticed it after playing the level Storm on H3 and every level after it. So far halo ce halo 2 halo 4 have been unlocking for me. So far any achievement not that didn’t trigger that wasn’t ties to level completion has triggered either an hour late or the following day but so far the game hasn’t triggered the second half of halo 3 story and the finish halo 3 on legendary achievement.
The achievements not unlocking actually aren’t a problem with the game, it is a problem with the achievements app. They will unlock in time, about a week or so. If you are really concerned about it the xbox support forums would be the best place to post.

I didn’t get an achievement for picking up a H2 skull, but I may have just done it wrong.
I was trying to get the IWHBYD skull in H2A and achievements just started popping up that were stuck at Done! Unlocking… before so I guess just give it time
