Could you please let me know when the update with this patch is expected to be released?
the actual bug is that instead of using the path yourtheme/woocommerce/wbte-eu-withdrawal-button/emails/<template>.php, they skip the wbte-eu-withdrawal-button folder (it never gets created) and the templates just get copied straight into WooCommerce’s emails folder — which is why it looks like the override isn’t working.
