Quantum Break achievement most important issues blocked

Same issue with Quantum Break for windows 10. Initally achievements were unlocked but after a few hours it does'nt work anymore...

Here is what you should do:

1. File a complaint on the GT breaking the rules

2. Block communications on the GT breaking the rules

3. Submit player review (avoid) GT breaking the rules

4. Move on (most important)

that is exactly how I feel. 1 achievement away from 100% and it does apparently "mark" the achievement as complete as far as the game is concerned, even though we clearly did not get it. I was considering deleting the save from both console and cloud and
re-playing the whole thing, but someone already tried that with no avail.

also no luck with hard reset or waiting the typical 72 hours

Browsing through some of the replies here, it's not limited to single achievements. For whatever reason if the achievement doesn't pop the first time around, no amount of replays appears to 'fix' the issue (it'd be mildly annoying to have to replay certain
parts of the game to get an achievement to retrigger - but this is much worse, I am only 1 achievement off 100% and this is due to a clear bug in the game/achievement system). Someone needs to take a look at the logic to allow these to re-trigger or re-test
the achievement (I'm guessing there's a flag on the save-game that doesn't match the Xbox Live Achievements somewhere).

for everyone having this problem, I just got the achievement.

no notification was given, I simply found out I have now 100% game complete.

I did the achievement on April 16 and it appears as done on April 28 so I can only assume that it takes around 12 days to finally see the achievement, whenever this happens.

as someone else said, "patience is key"
