A tracking page that has not updated in the early days of a shipment is common. A label is often created before the carrier's first scan, so there can be a gap before anything appears, and international shipments can move slowly between scans, especially around holidays and weekends. In most cases it catches up on its own.
Delivery times can vary depending on the carrier. If your tracking has genuinely stalled for an extended stretch, get in touch with support@vagustim.io with your tracking number and we will look into it.
