We understand your frustration that you were only approved for the quests despite your best efforts. Our quests are in high demand and highly competitive as our Stackies seek to be rewarded for their efforts.
We receive a large number of submissions and we reward submissions based on a first-come-first-served basis. Once the rewards have been given out, the rest of the submissions are approved.
If you wish to be rewarded, we would advise you to attempt the quest and submit it as early as you can. Generally, our Stackies who submit on the day of the quest start date have a very high likelihood of being rewarded.
