I figured it out. I did not know I needed to be logged into AliExpress at the same time while placing the order via woocommerce from the WP dashboard. Ir makes sense.
Thank you for the support and quick responses, I do appreciate it.
I've clicked through to the order page and there is no button on the top right that says - auto order. See screenshot.

So how do I get to the auto order button?
Thanks
