Agent
Thank you, please let me search the account real quick.
Me

Me
the beginning task is so easy to finish…
Agent
Oh thanks for letting me know, let me just ask my friend, when did you unlock the achievements?
Agent
Oh, you are so amazing my friend
Me
1 or 2 hours ago, i finished the task
but the achievements are still unlcoked
Me
not unlocked, they are still locked
Me
i already reset the xbox app, nothing happened.
Agent
Oh, thanks for the details, may I know if you have seen that the achievement has been unlocked?
Me
no
Agent
Because there are times that it will take 72 hours before it will be unlocked.
Me
the time issue?
Agent
Oh I see, you need to make sure to see that the achievement has been unlocked. May I know the title of the achievement that you’re trying to unlock?
Me
ok
“welcome to base camp” it requires “open the blizzard mountain festival”
Agent
I can go ahead and check for the tips on how to unlock the achievement. May I know the title of the achievement that you’re trying to unlock?
Agent

Me
and “welcome to horizon hot wheels” etc…
Me
these tasks are simple, just buy the DLC and play it, you can make it.
Agent
Thanks for waiting. Yeah, you should be able to get this achievements and it should pop up when you access it. Are you in-game right now?
no
Me
yes, you are right
Me
now i am not in game
Agent
Ok, please try to sign out then sign back in from the game
Agent
Then try to access it. If there’s no pop- up that will show that the achievement has been unlocked, we are afraid that we may need to wait full 72 hours for it to appear
Me
