Amazon results

Hi David :)

I am testing a simple installation in basic version 18 / 06A.

Everything works fine except for a small problem that I can not solve.
I installed the Amazon responsive API. The keys are good and active.

When I do a test with the url:
{link saved}
I have many results.
But when I click on the logo in the product page, nothing happens.

The url, for example:
{link saved}

On the Amazon logo:
{link saved}
Nothing changes...

Another example:
{link saved}
No results, but if I run the url:
{link saved}
I have many results.

Can you help me understand why nothing is displayed?
I tried with FF, Edge, Chrome, Waterfox ...

Cheers,
Raoul
