So here's how I made it work. In Edge, as before, I chose a product, got a blank page and no further action. So I copied the address out of my web browser and pasted it back. The program advanced, I did a few steps, then signed out. When I logged in again I was where I left off. So there is something about the program that is keeping it from advancing automatically beyond the page that comes after the one where the product is chosen.
