We are currently facing the same issue with them. We have licensed a video twice for one of our customers, yet the claim still persists. We have followed all the correct procedures, obtaining one license for a specific video.
We have already submitted a ticket on Envato’s website, reached out directly to the author, and even opened a dispute on YouTube. Unfortunately, we have received no resolution so far. If they do not revoke the claim, we may have no choice but to take legal action against both Envato and Elite Alliance, as our customer is considering this course of action.
We strongly believe that Envato should ban such authors and companies from their platform. We have come across numerous similar problems with them, and it is clear that selling something without honoring the rights associated with it is fraudulent. This situation is disappointing for Envato as well, as it reflects poorly on their platform.
After more than five years of working with Envato, four years on another account and one year on this one, we are contemplating using other services that either manage such issues directly or take responsibility for such cases.
