It's been 28 days and the review is not completed.

Review times vary based on how many assets were ahead of yours in the wait queue when you submitted.

On average, Photos & Vector Graphics are reviewed by Adobe Stock employees within 5-15 business days.
Illustrations & Generative AI could take 1-3 months due to the backlog of submissions.

Everyone must wait their turn. Meanwhile, work on other projects while you wait.

As a side note: review hasn't started yet. Moderating a picture takes only a few seconds.

You are not addressing Adobe directly in this forum, and you will not receive a reply from Adobe as to exactly when your submissions will be reviewed. The 4 weeks estimate that you saw when you uploaded is most likely the average wait time for all types of assets. Generative AI is taking 2 months or longer, while other assets types, such as photographs and videos are reviewed faster.

Adobe moderators moderate submissions in a first in, first out manner. If your assets have not yet been moderated, that means that other assets have been submitted before yours. By the way, the time shown on your screen is based on the upload time, not the submission time. The text shown is erroneous.

According to Adobe, moderations can take up to 2 months currently. So be patient, your pictures will be, when accepted, open for sales for an eternity.

We are not Adobe. We are contributors like yourself and there is nothing we can do to hasten the process for you. Many here are all in the same boat when it comes to the waiting. Two months is average if you are just starting out with your first submissions.
