HELP PLEASE!!! Achievements won't unlock at all!

That's a bummer. Sometimes restarting the console helps. Or if it says "Done! Unlocking." You have to wait up to 72 hours.

Hi there CptRedbeard220

Please check out all the steps in our forums sticky for
achievements not unlocking. These steps can help to unlock the achievements, it can also take up to 72 hours for the achievements to unlock. If the achievements have not unlocked after that time you will want to fill out the survey in that link as well.

I haven't had any problems with the achievements unlocking thus far, except for the Manager Tasks in FUT. I unlocked them all in the 360 version, still unlocked in the One version, and it won't give me the achievement.

I have to add, that since the achievements were unlocked in a unlegitimate way, the gamerscore for the account will likely be reset in the future.

Which means all unlocked achievements for all games on that account will be reset to 0. You won't be able to get earn achievements again with the account.

Also keep in mind that if you're playing offline with no connection at all, achievements won't unlock
