I’ve just got another variant response. Using Edge (which I’ve used far less than even Opera), I see a rectangle of the same size as before, but this time with a light grey background, and in the foreground, there is a large, simple icon in black, showing a rectangle in portrait orientation with a corner folded over, thus obviously representing a document, and on top of it a symbol like a road traffic “No Entry” sign, i.e., a circle with a diagonal bar.
