ISSUE:
ESID: ESHK18665644.
Description: The courier went to our billing address instead of our pickup address. This bug happens occasionally and still daunting us. Please fix it.

Detail: We were using the origin_address_id attribute in /shipment/v1/shipments api. However, courier get notified of our billing address instead of pickup address. This causes trouble quit a lot.

Thank you
