How can undo an image I licensed by accident?
Unfortunately, there is no way to unlicense an Adobe Stock image.
Can you please share the file ID which you have accidentally license so that we can further assist you?
This happened to me as well. IMPORTANT TO KNOW - they only gave me one exception, I am not allowed to make this mistake twice. It is very easy to do because I mistook the purchase window for premium assets to be the same as my standard license subscription. I realize now I wasn't paying close enough attention. Had the window been a different color, larger, even a stop sign graphic - anything more obvious than a light gray window would have helped alert me to what I was getting ready to do. I would like to recommend to the Adobe team to look for other really obvious ways to have the premium assets differentiated from the standard ones.
