I have ended up getting involved in Amazon bits from time to time as from a client's point of view it's all e-commerce. They are an absolute nightmare to deal with. Everything is opaque, everything takes however long they want and changes you make as a seller, even as a registered brand owner are merely a suggestion that even if accepted may be rolled back half an hour later with no notification. The whole platform is at the mercy of bad actors (of which Amazon themselves are the worst) They then squeeze for the highest fees they can get away with - the bulk of their expertise being used to work out stuff like this rather than delivering any kind of positive experience to their suppliers. Over the years I have built a hatred of them.
