Cannot license asset in-app
This doesn't help when the stock image was used in a composite and all masks and adjustments have been set but the image just wont go from the preveiw to the licensed one. I'm having this problem as well. All other images I've licensed quickly update from watermarked to licensed but there is one that will not. I've added all images in the same manner but one wont convert. My only option is to rework the art with the licensed version and that is unfortunate and wastes time.
