I just received a mail saying: "We see that you’ve uploaded 1 assets to sell on Adobe Stock, but may still need to index and submit them. It’s fast and easy — and it’s also required for selling your work. As soon as you index and submit your assets, we’ll be able to review them for approval."
What do I have to do?
Make sure you have added keywords to your assets - photos etc. If you have already done this and submitted them, don't worry about this email.
