Hello Pavel,
Sorry for replying late.
Thanks for your timely support for the community.
WooCommerce 3.3.4, WordPress 4.9.5, ATUM 1.4.1.2
1. We see very big differences, like sales, products and orders numbers are approximately double than what is showing in woocommerce reports.
2. Actually we have introduced the new products (some days after ATUM is activated in our store) and they sold out completely within hours and it’s been two days that the lost sales and out of sales days are not showing.
Thanks in advance pavel.
Eagerly waiting for your kind reply.
(PS: We have installed ATUM in february and deactivated it; as we were waiting for the new managing system regarding the variable products)
