Subject: WooCommerce 11.0 ships its own email verification – customers are now asked twice

Setup: WordPress with WooCommerce 11.0.0 and your plugin handling double opt-in at registration.

WooCommerce 11.0 introduced AutomatticWooCommerceInternalCustomerEmailVerification. It renders a prompt on My Account → Orders (hooked to woocommerce_before_account_orders) for every logged-in customer whose address WooCommerce does not consider verified. Its state is entirely separate from yours, and there is no filter to disable the prompt.

The result: a customer who already completed your double opt-in is asked a second time, by a different system, to confirm the same address. It looks broken and it undermines trust in your actual verification email.

Suggestion: when your plugin marks a user as verified, report that to WooCommerce as well – guarded, because the class is internal:

$class = 'Automattic\WooCommerce\Internal\CustomerEmailVerification\EmailVerificationService';

if ( function_exists( 'wc_get_container' ) && class_exists( $class ) ) {

wc_get_container()->get( $class )->mark_verified( $user_id );

}

We are aware this depends on an internal class and have raised the missing public API with WooCommerce separately.

A related point while I have your attention: WooCommerce logs new customers in automatically after registration (woocommerce_registration_auth_new_customer). We had to add our own filter to suppress that while verification is still pending. Handling this natively would remove custom code from every WooCommerce shop using your plugin.

By the way - your layout seems to be broken in some way...
