This would have nothing to do with the rejection as it is game related, but I am interested in what Niantic has to say about this appeal. I think they still say an updated “mural” should be edited, but other poi need to be removed and replaced. However when I tried to correct the name of a rotating artwork, they said it was a new artwork compared to the one that had been approved, rejected my edit, removed the Wayspot, and told me to resubmit it. I think this new wrap on the same utility box is the same situation as my new artwork on the same frame that they removed, and am wondering how they will rule here.
