I'm new to Adobe Stock by just a couple days and today I decided to browse and start saving previews for future use. Twice I've accidentally licensed images and I can't find an undo button. The first one is image 59880541 and the second one is #66935895. These images are useless to me. Is there a way to get a credit back on my account? In the future, is there a way to undo this myself as soon as I realize it happens?
