Infinite scrolling not working anymore

Hello,
for some time (I only noticed it yesterday, but it certainly always worked in the past)
https://dev.letsleds.nl/led-verlichting/ondiepe-inbouwspots/

Could it have been an update?

Here are the settings:
Navigatie Muis .sorting-end
Volgende Muis .woocommerce-pagination a.next
Item Kiezer .mainproduct
Inhoud Selecteur .content-area
Event Type Infinite Scrolling

Thanks!
