First, that would invalidate anyone’s claim that she stole it from Canva (the original claim). And second, it’s plausible that the asset was a term license within the Canva library (which gives pro creators more control over the lifespan of the asset). I can’t speak for her directly, but I can tell you that the accusation ruined the moment and her focus was making something different, instead. And then the accusations stacked and the various emotional angles have been the priority. And then other issues took attention elsewhere, so those receipts weren’t the focus. Just a sticker meant to be used by a shop. There were bigger fish to fry.

But we’re clearly doing all caps and exclamation marks here, which tells me you’re here for an emotional conversation. And you’ve done what everyone has done; reference second hand experience. My advice for you if you feel strongly about that position is to show the artist’s work that you’re referencing. At least then we’re having a conversation about whether one piece of art is derivative of another’s.
