When we addtracking to an order, and we "marked as shipped" an order, it says: "notify customer=true" but our customers are not receiving emails. They only receive emails now if we create a label now through shipstation. Any idea how to fix this issue? We are blind CC on all customer notifications. Even if we try to resend notifications it will not work. Our marketplace is Magento 2, and the information does get updated on the marketplace side since the order gets moved to "complete". We rely on Shipstation to send the confirmation email to our customers.
