At the risk of getting banned from the forum for having too many problems:
Today, I sold two items. Just two. And both of them – 100% – are showing up in GS7 as having not sold, or black rectangles. (The Vintage Costume Jewelry and Vintage 100% Silk Shirt Dress, at the bottom of the screenshot below.)
So, it’s gotten different, but no better.
Perhaps you would consider adding a feature which would allow us to change the color of the rectangle when GS is inappropriate in the designation?
