Please query your address first to see if you are qualified to withdraw airdrop before August 28, 2021.
If you finished the airdrop tasks, you can click to withdraw.
If you think you indeed finished the tasks, you can report to ask for review.
After 24 hours, you can try to query and withdraw again.
If the result is not approved, it means that you didn't finish your tasks after at least one moderator reviewed. Therefore, there is no report to review service provided for rejected airdrop.
