Xbox unlocking achievement problem

Hello BlakManDan, there was a problem yesterday with Achievements not only yourself were having these problems but everyone else on Xbox one. Your Achievement should unlock by itself in a couple of days some are already unlocking for others. I've had this
problem too and my achievements unlocked after awhile no need to worry .

Hello AchievmentMunky, 343 did say they were having problems with Achievements not unlocking for players they are aware of this problem and are looking into a fix. Some of mine started unlocking the other day but some still need to unlock. Also today Xbox
had a problem with Achievements unlocking so if you got any today this also might be why.

Hi Black samurai

sometimes there is a delayed effect in unlocking achievements on xbox sometimes they can take anything from hours to days to unlock if there is a problem, also check your achievements to make sure that achievement is unlocked in your list hope this helps.

Hi TheGeekyBanana, achievements not unlocking is common with the Xbox One. Some users unlock them fine, while others don't. Microsoft are aware of the problem, and are working on it. Worry not, as your achievements will unlock eventually, I know as I
waited for achievements to unlock for Destiny, and they finally did a few days ago.

Hi

Wait 24 hours for the achievement to eventually register, if this problem persists, there may be a few implications, one is that the achievement itself was not completed as specifically as it was created by the developers to be done, or there is a problem
with the achievement unlocking.

Doing some quick digging online, it appears some achievements just refuse to unlock for this game, both on the Xbox and PC versions, some have cited future attempts at the achievement give a successful unlock.

I would suggest looking up a guide for the achievement and compare that you did the steps necessary for unlock.
