// That's all folks!

Thanks @BFTrick for the idea and especially thanks to @PegWeb who has solved the problem that it was sending the old data instead of the new one.
For me it works correct like this

I added this in order to evaluate if there is made any changes - feel free to copy

/*** add hidden field to frontend edit billing address form */
function my_custom_woocommerce_before_edit_address_form_billing(){
echo '';
}
add_action( 'woocommerce_before_edit_address_form_billing', 'my_custom_woocommerce_before_edit_address_form_billing' );

and then you can simply replace

if ( empty ( $email ) ) {
return;
}

with

if ( empty ( $email ) || $shipping_address == $_POST['$old_shipping_address'] ) {
return;
}

not tested

I need a solution like this - but when customer change address in checkout - please let me know if you know how I can do that
