3D Secure Not Working Properly – Endless Failed Payments

I’ve been running around in circles with both Stripe and Woocommerce on this. Since March if a payment is determined to require 3D secure, it’s complete fluke as to whether the popup modal will appear. For the customer when they click checkout nothing happens until the end. Keep being told that it’s a plugin conflict, but I’ve checked all likely conflicts and cannot find anything – it was working absolutely fine pre the last update in March and no new plugins have been added since.

Lost tens of thousands in revenue since then and Stripe are about to lose a several million in annual transactions if it’s not imminently fixed.
