We have been using Amazon Shipping in shipsation for nearly 6 months now and are still facing the same errors when processing orders. Amazon exports a phone number with an extension for every order. Because Amazon Shipping cannot have more than a 10 digit phone number, we need to manually delete EVERY custom phone number or at least remove the extension. The common error we get is below:
Amazon Shipping US: 1 validation error detected: Value at 'shipTo.phoneNumber' failed to satisfy constraint: Member must have length less than or equal to 20 (Generic). (400, 222772c6.........)
Is everyone who is using this feature also manually deleting every customer's phone number? I can't figure any type of workaround and this seems to be such an easy fix for Shipstation.
