I've been waiting for 8 days for my photos to be accepted on Adobe Stock, is this normal?

We forum volunteers, who are Contributors just like you, have no way of knowing that. Some assets get approved quickly, some wait for up to 2 months. It all changed when Adobe started accepting Generative AI assets ~15 months ago, flooding the system with massive numbers of assets to be reviewed.

In 2020, you did not have fellow contributors uploading thousands of assets per day, due to generative AI, that made it possible to create a would automatic workflow.

It all changed, and when you compare your old asset IDs with the new ones, you see how much assets have been uploaded meanwhile.
