Click-event for special class not tracked

Hi there,

Cool plugin. Especially the scroll function looks pretty advanced.
My only problem is that I cannot make a certain very important class get tracked.

Full disclosure: I have no coding skills and the button/link I am talking about is created by WooCommerce. I use WooCommerce with external products so instead of adding products to carts people click on “Go to Link”-buttons. These buttons have the class “single_add_to_cart_button button alt ext-link”.

I tested the plugin with other elements using both IDs and classes and it worked just fine.

Any advice? I would also be okay with adding IDs to every single of these buttons, but I seem to have no access to that code.

Cheers,
David
