Xbox achievement didn’t unlock

Hi and thanks for reaching Microsoft Xbox gamer's community. My name is Josef.
I'm an Independent Advisor and a Microsoft Xbox user like you.

Hope you're doing great today despite this Matt

Sometimes an achievement can take up to 72 hours to be reflected in your profile.
May I know when you completed it?

Also, did you already tried everything from the achievement troubleshooting steps?

Same for me , i made 4 achievements and it didn’t unlock the reward . Also for the Gears 5 quest ..

Xbox 360 games played on the original system itself don’t require an active broadband connection to unlock achievements, unlike Xbox One’s backwards compatibility. Unfortunately your account maybe under a temporary suspension or you didn’t meet the
requirement for the achievement itself

Hi there, LemonLaime. It’s unfortunate to know the achievement’s troubleshooting guide didn’t work for you.

In the rare occasion an achievement doesn’t unlock even after waiting a few days, the recommended action is to report the inconvenience to the Xbox team:

Sorry to hear that I have experienced similar problems in the past. I recommend clicking on that specific achievement, turn your console off and then after you turn the power back on, click back on the achievement then within a few days any delays\problems
etc. Should appear, hope this helps. DylanXXVIII28 ��
