Achievements have not unlocked after a week

There are three achievements in Halo: The Master Chief Collection that I earned on the game's release day (Nov. 11) that have not unlocked yet. Other achievements that I earned that day have unlocked and every achievement I've earned since then has
unlocked. I know that server issues can cause achievements to get delayed, but a week seems like a long time, especially since others I got around the same time have unlocked.

Achievement Unlocking Issue

I've had this once in Star Wars Battlefront 2.

Achievements was 100% done, but not unlocked.

It unlocked randomly within a week.

 

Missing Phantom Breaker: Battle Grounds Achievements?

My Phantom Breaker: Battle Grounds Achievements there are also problems

I have all the achievements unlocked

Do not know why the DLC achievements showed me not unlocked

Compare game achievements with people i can display 500

Game seen achievements unlocked 38

but the the achievements of other places to see only display 400

The date of this problem is found 2013/4/6

A Perfect Fall achievements unlocked date should be 2013/4/6

But the Xbox site and A Perfect Fall achievements unlocked 2013/4/7

After so many days still did not fix my achievements

 

I have the same issue. Achievements I earned that same day/other days have unlocked but I have this one achievement for beating the level 343 Guilty Spark on Halo CE that won't process even though it says "Done! Unlocking..."

Its been about a week now.

 

I had an "ambassador" reply in a thread I started that it is a system issue. I have been told four different reasons why they are not unlocking but really don't believe any of them anymore. I haven't done any serious coding in some time but every programming
language I have ever used had some form of the if then statement. If achievement flag says complete then unlock as an example. Seems like not that big of a fix.

 

Yeah I have 8 achievements that I completed on launch day (Nov 11) and as of right now are still "Done! Unlocking..." Originally I had like 15 Achievements that were bugged but half of them started unlocking throughout this last week, I would really like
those others to hurry up and pop sooner rather than later...

 

I'm having the same problem and it's happened to me since launch as well. Almost two weeks now and I've been stuck with a done...unlocking message on more than one achievement. Can there not just be a server refresh ore something. I don't know how it works,
but if they could just have our xboxes re-send the requests to unlock an achievement, shouldn't they? I don't want my progress to be lost in the nomansland of a server as an outdated request that will never be filled. It's affecting my experience of the game
and my frustration with the console has only been getting worse. Please fix this. I've tried everything, and wasted a lot of time and my friends and I are becoming disillusioned with xbox as a gaming device. It is not asseamless as it is made out to be.

 

Same here for me but they unlock when I play the mission again.

Hope this helps!
