Hi,
I wondered whether Atum Inventory Management for Woocommerce 1.6.0.1 (latest at the time of writing) is compatible with Woocommerce 3.7, which has been out for a while now. The Woocommerce update notification in Wordpress warns that Atum has only been tested up to version 3.6.4.
Kind regards,
Henk de Kruyff
