Cart issues

Hello,

I have a WooCommerce / DIVI website with LiteSpeed Cache and https://www.ads-software.com/plugins/side-cart-woocommerce/ cart plugin. I’ve been experiencing an issue where my customers report that items they’ve added to their cart disappear when they click on “Checkout.” The issue seems to be random, as everything works fine when I test it myself. I’m at a loss for how to resolve this issue. Do you have any suggestions or can you assist me?

Cache is activated with ESI and I have already tried to exclude all WooCommerce cookies from settings as well as pages.

Thanks a lot.
