If you believe you are missing rewards, please log in with your Xbox Gamertag to the Road to Gears 5 page and verify the status of the Challenges associated to your missing content.
In order to unlock any retroactive Challenges, you must have logged in to Gears of War 4 during the active Challenge dates to unlock the associated Challenge. We are unable to award content to those who did not log in during this period.
If you still believe you are eligible for content that is missing, please reach out to our support team.
