For orders that have not been split into multiple shipments, you can use the "Amazon Logistics" provider in the app:
- put something as tracking ID (doesn't matter what, e.g. "a")
- choose your regional Amazon website (e.g. "Amazon.com")
- enter your Amazon order ID (format like "303-4564564-1212121")
If you want to go the extra mile for split orders, you can extract the internal item ID from the "Track package" link next to each shipment in your order overview. The item ID is the part of the URL after "itemId=" with a format like "jipisojquroruo". Put this as tracking ID for the Amazon Logistics entry.
