I know how valuable time is for you and the relevance of the shipping manager, @HelloRose.

Currently, we are transitioning to a new shipping experience for all customers. If you haven't been affected yet, you can still use the Old Shipping Manager.

Once the new shipping experience is available, the system will automatically remove the old shipping tool and all related information. However, you can access shipping-related tasks, like voiding labels, directly on the carrier's official website.
