No, There is no way you can unlicensed an image once purchased.
We have already noticed the same issue of one clicking License method, and our engineering team is working on the same.
I agree! I just licensed an graphic I have no interest in. There should be a confirmation option to licence and/or a user option to unlicense.
Has there been any updates to fixing this issue? I just did the same thing and I'm mad because it's such a dumb image.
