Woocommerce "Order updated" trigger only runs when order status is updated

I have come to the conclusion that the Woocommerce “Order updated” piece only triggers if the status of the woocommerce order is changed. If a custom field is added/updated or if a comment is added to the order, the flow doesn’t run.

Is this expected behaviour or a known bug?

@abuaboud I’m still struggling with this issue. Do you have knowledge about this?
