Styles not working in production

Hi! We deactivated WP Better Emails because it was causing vulnerability issues and replaced it with WP HTML Mail – Email Template Designer. Order Confirmation emails are working fine in staging, but in production, they don’t have the style assigned.

WP Better Emails had this code that was commented on:

add_action( 'phpmailer_init', 'better_phpmailer_init', 20 );
function better_phpmailer_init( $phpmailer ){
	// this filter will return true if the woocommerce_email_header action has run
	if ( apply_filters( 'better_wc_email', false ) ){
		global $wp_better_emails;
 
		// Add template to message
		$phpmailer->Body = $wp_better_emails->set_email_template( $phpmailer->Body );
 
		// Replace variables in email
		$phpmailer->Body = apply_filters( 'wpbe_html_body', $wp_better_emails->template_vars_replacement( $phpmailer->Body ) );
	}
}
