Problem: when we create order via POS register, system changes order tatus from on-hold to processing instead completed . None of functions or plugins like Woocommerce Order Status Management are not helping. Order status is staying processing.
Solution: Code changes in original class-wc-gateway-cod.php file were provided.
Statys on-hold was changed to completed
Path to : class-wc-gateway-cod.php file /wp-content/plugins/woocommerce/includes/gateways/cod
This change is temporary and code has to be updated EVERY TIME when woocommerce plugin has updated !!!!!!
