Achievements not unlocking on FIFA 14

Titanfall, Dead Rising 3 and forza 4 achievements progress has gone. Also got an achievement in FIFA 14 but it didn't unlock. Hopefully an update will come soon !

Same issue with different games on XB1, i have two unlocked achievements today in Dead Rising 3 but the points are not added to my general Game Score, another achievement is 100% complete but not unlocked, same with another achievement in BF4 100% complete
and not unlocked, another one in Fifa 14. This is very frustating, too many problems with this console.

EA's customer support has to be the worst out there. On the One, there is an achievement in FIFA 14, that if you unlocked it on the 360, you can't unlock it on the One. EA's response to multiple threads in regards to this was, "Talk to Xbox Live Support
about it." Brilliant.

I feel your pain, OP.

Achievements unlocked as of 8/10/14. They are also showing their original unlocking date. I do not know if it was fixed by the Microsoft advocacy team or if they achievements automatically unlocked.

Overachiever on 8/6/14

Perfectionist on 7/6/14 - The crazy thing about the one is that it unlocked over a month later.

If addition to what Smwutches has provided, Killer Instinct is free to play but you can't unlock achievements unless you have one of the packs. Additionally, you can say "Xbox, Bing", then say "Demos" and you will see there are 4 demos currently available
for download: Zoo Tycoon, NBA Live 14, FIFA 14, amd Kinect Sports Rivals.
