Order status no info "No orders found"

This is weird because I have the exact same set up on another website and it works fine, but not on this one. Basically when I sign in and buy an item it does not get displayed in the order status section, it just says “No orders found”. Anyone know why? Or maybe I’m missing a step. Again, I had it working on another site…
Thanks!

Can you try switching on the Testing Mode option? It is likely you are making test orders but are looking at the live screen.
