I don't think it's happened on any of my stories. This is what I hate about Medium - lack of total transparency when it comes to how writers earn money here. Sounds like they don't want to keep paying you for claps once you've been paid on past claps. I can only speculate since I don't have all the facts due to this lack of transparency. And one of many reasons why I won't chase money on this site. The cards are basically stacked against writers and designed to fill Tony's pockets. If I'm mistaken on this belief, then he needs to 'splain himself. I'm all ears. Hope I'm wrong.
