Despite the fact that Amazon is no longer supporting the PC and Mac market place from Oct 2018 I thought I would go ahead anyway and upload my product just to see what would happen.
After spending quite a bit of time entering the product description, I hit save to proceed to the next stage. Then a message flashed up about some undescript error, and the page reset itself loosing all my data. This breaks the cardinal rule of all software development. "thou shalt not loose your customers data". Good manners forbids me reproducing the expletives.
I am done with Amazon.
