Dear Latrat, dear Perchpole,
The latest stable version does NOT yet use WooCommerce's shipping zones, as it already has a similar functionality built in. See
open-tools.net/documentation/advanced-sh...ce.html#installation
However, the latest pre-release version 1.2.99 (to be released as the next stable version 1.3) contains full support for shipping zones. If you want to test it, please download the pre-release versions from the product pages of the "Shipping by Rules" plugin and the paid "Advanced Shipping by Rules" plugin:
open-tools.net/woocommerce/shipping-by-r...for-woocommerce.html
open-tools.net/woocommerce/advanced-ship...for-woocommerce.html
Please be advised that this is a pre-release version. We are not aware of any issues, but we wanted to get some more tests from different users before we let the whole user base automatically upgrade to that version. In our test, the plugin works just fine. If you decide to try that version, please let us know whether everything runs smoothly or you run into any issues.
Best regards,
Reinhold
