I installed a plugin called woocommerce customer manager in order to have a more indeep view of my customers behavior, then i realized it wasnt working correctly, the plugin wasnt showing my customers assigned orders, then i tried to look in the default woocommerce panel and the same thing happened, when i filter by customer i get 0 results.
Thanks in advance!
