The affiliate plugin installed has feature to track sales of affiliated when checkout using woocommerce, where each affiliate gets their unqiue link with UTM like sitename.com/?abc=1 where this UTM would track the traffic and when customer clicks checkout pays and completes order it should auto credit affiliate balance with commission but since at checkout page that is sitename.com/checkout it simply overwrites UTM and at end page after payment it becomes like https://sitename.com/checkout/order-received/427999/?key=wc_order_WPTn5WSPKv9Kg which then again double overwrites any UTM if got to that point. Which i think might be main reason why affiliates sales are not getting auto credited with commission??
