My xbox one achievements does not appear in my gamerscore

Hey, sorry to double post but I wanted to post on here too that my gamerscore fixed itself. All I did was play a new game I just bought today "Monopoly" for the Xbox one, I got all 1000 gamerscore today, checked my profile and saw I had somehow reached 143k
when I was at 137k so... I was very happy, haha. Just keep playing games unlocking achievements and hopefully yours fixes itself too.

This also happened to me, which I have reported to support also. They told me they were going to work on figuring out what happen. They can't exactly fix the achievements on their end. I believe it had something to do with syncing the achievements. The day
I noticed it I hadn't even gotten on the Xbox one at all. The gamerscore lost is all from the Xbox one, and only the gamerscore achieved before it occured or "Glitched" I'll just call that.

It's just weird that as I unlock achievements for the Xbox one it counts them towards the "Xbox One games" category in the Xbox 360 achievement list, but doesn't even recall the previous games. If anyone else has this issue please post here or contact support
and give them as much detail into this as you can. This could be a growing issue and hopefully we can get it fixed.

I have this same issue. Started around a month ago. Whenever i play an xbox one game for the first time the game doesnt appear on my achievement list but a 360 game does. The achievements appear in my recent activity and i get the gamerscore though. Ive
spoken to xbox support today and gone through all of the steps and it still doesnt work. My gamertag is . Please can someone fix this.

Hi StrategicMisfit,

Yeah, your right. I have earned Gamerscore on the Xbox One. Earning an achievement while using the Xbox 360 provides a fix, although a temporary one.

The appearance of lower Gamerscore is still found after clicking "A" on my Avatar from the Social Hub and going to the Right once. This is the secondary location of Gamerscore on the Xbox 360 console. After earning an achievement the Gamerscore that displays
in this location is lower than the one shown next to my Avatar within the Social Hub.

Additionally, downloading the Gamertag using the Xbox 360 will cause the Gamerscore found next to my Avatar within the Social Hub to appear as the lower value as found in the Gamerscore's secondary location.

Let me know if the same issue occurs on your end too.

The achievement list on Xbox One appears to be viewable again, but now with less functionality:

-360 games with zero gamerscore that were previously deleted, have reappeared and cannot be deleted. Deleting them again on the 360 does not remove them from the Xbox One list.

-The order of games on my achievement list has been randomized.

Everything on my list from 2007 - Oct.2011 is randomized and not in the 'date played' order it used to appear.

Games I haven't booted since 2008, have strangely been moved up as if played in 2015.
