Problem with unlocking achievements in xbox one

I am having similar problems the game shows I've unlocked all but one achievement however when checking achievements on the Xbox one, true achievements, or achievements from the phone they all say 16 of 20 unlocked. I just unlocked one yesterday and it showed
up everywhere

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 .

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.

I've still had achievements unlocking for me. Maybe there is a problem with a specific achievement? Perhaps you should post about which achievement and see if anyone else is having problems getting the same one to unlock. That's definitely happened in the
past with other games where specific achievements would not unlock and the developers were able to fix the problem.
