Most Files Still Pending, Only a Few Rejected as Similar

10 days is not a long time to wait. I have some files that have waited for months. If you contact the support team on this subject, you'll just get a canned response.

This is what Adobe Stock has to say about "similar content."

Before you submit, always check your work against other inventory in the database. If Stock already has many millions of similar assets, they probably don't need more, unless yours is very special in some way.

Also look for less common keywords & titles with which to label your assets.

Hope that helps.

"Normal" review time is 8 weeks. Sometimes longer. Sometimes within 24 hours.. There is no need to contact support. It's just the way the review process is these days. If they sit in the queue for more than three months, they might have gotten stuck. Delete them and re-submit.
