Dragon Quest XI - Final achievement (for getting all other achievements) will not unlock

There are achievements but the actual achievement list isn't live yet for some reason.

Just play the game & you'll unlock the achievements,i've unlocked 3 already.

There aren't any missable ones if the achievement list is the same as the PS Trophy list.

I'm having a similar problem this month with the ID@XBox quest. You need to unlock four achievements in ID@XBox games; I unlocked four in Human Fall Flat. The individual quests (one for each achievement unlocked) all have the green checkmark with the word
"complete", but when I try to click the box to claim the 400 reward points, nothing happens. I've unlocked several achievements in another qualifying game since then- Manual Samuel. Still nothing.

I had a problem with one of the quests from a few months ago that asked you to unlock an achievement in any Game Pass game, then to unlock five more in any combination of Game Pass games, and finally to unlock fifteen more achievements in any combination
of Game Pass games. The quest was worth 600 points. The final box (for unlocking 15 more achievements) never showed as completed. I kept trying all month, expecting it to say "complete" with each new achievement I unlocked, but it never did. I checked
my progress for the month on True Achievements, and found out I had unlocked 75 achievements in Game Pass games for the month, but I missed out on the 600 reward points. I don't think waiting a few days will make a difference. I hope I'm wrong.

Unfortunately all sales are final. I will also re-state that other people have successfully unlocked this achievement. There are videos on youtube--and other sites I'm sure--of the achievement unlocking.

Mine registered the one I got. Unfortunately I have owned the games since release and have majority of the achievements unlocked. Just beat it on broken bones and that was the one achievement I unlocked and it counted towards the reward. All the other
achievements left are all the super rare ones. Not sure I will get the 200 points before the quest expires.

I love game pass quests. It gets you to play games you might not play. However the only bad quests are the ones that have you unlock achievements for a certain game, especially if you have already unlocked all of that games achievements.
