No Amazon Sales

I’ve got a bit of a dilemma. I recently started selling on Amazon (sold on Amazon UK first) and was very successful with my first products. I sent a variation of this product to Amazon France (they sell between 500-800 per month) and matched the lowest price. Absolutely no sales. They were taking their time in transferring them between fulfilment centres and there are now 5 available out of 10. However, they’ve been available for four days now and absolutely no sales still. I was thinking perhaps it was because I needed to verify some information on my sellers account which I completed today. Could that be the reason why I have no sales? Even though my listing is actually active on Amazon France? Thanks for any help.
