Why is my Meta Pixel not tracking add-to-cart events from my Shopify slide-out cart?

Slide-out drawer carts fail to fire add-to-cart triggers when your theme relies on asynchronous AJAX requests that do not reload the page, bypassing standard browser-side trigger events.

“The real issue underneath this is your slide-out cart loading via AJAX, so it never triggers the page-reload event your pixel is waiting for. I’ll wire up the right trigger within 24 hours for $99.”
