If you've been selling on a Amazon for a while, you probably have first hand experience with the "Flywheel Effect", the delicate cycle of sales velocity and success, that could either turn vicious or virtuous, depending on the smallest action or inaction on your part. Just like the laws of physics, a product in motion tends to stay in motion, and a product at rest tends to stay at rest.
Success on Amazon requires fast responses to customers and Amazon itself. It requires you to inject energy into the flywheel, by almost any means necessary, to get it moving. And then, steady effort to keep it that way.
