Can't unlock FUT account on Xbox one

I also got it in FUT. I can't really offer much assistance though, sorry. I wasn't trying to get the achievement, it just unlocked.

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.

You may wish to look here - https://www.fifauteam.com/fifa-18-carryover-transfer-guide/ This is how EA have chosen to impliment the game, and not Microsofts.

You didn't say what FIFA version you were using on the 360 but I think one of these applies.

Same Platforms, from FUT 17 to FUT 18 or from FUT 18 to FUT 18

• 
  From XBox 360 to XBox One (FUT 17 -> FUT 18)
  
  From XBox 360 to XBox One (FUT 18 -> FUT 18)
  
  You no longer can share your stuff between different consoles, even if you are still playing on the same platform. This means coins, club items and transfer market items will no longer be shared between Xbox 360 and Xbox One, and between PS3 and PS4. You’ll
  only keep what’s linked to your Origin account. That is your XP and FCC.

You can't. Please put FUT or Ultimate team when you need help with FUT. Those blue backgrounds are just limited editions (Man of the Match, TOTW, TOTY, ect.)

Hi Jerry,

Thank you for posting on the Xbox forums.

FUT is a feature in FIFA games that is managed by EA through your EA account, which should be linked to your Xbox Live account when you first start up a FIFA game. The FUT application is also managed by EA so I'm not sure what restrictions could be in place
for child accounts, but either way I'm pretty sure the FUT application requires you to log in to your EA account, not your Xbox Live account and this could be the issue.

I recommend contacting EA customer support or post this same topic over on the FUT Xbox Community forums to get an answer from other Xbox FIFA players like yourself:

I hope this helps!
