I can confirm that this functionality has now been implemented into the system.
During this month we are migrating all clients to the new Amazon sync and once migrated you will start to see the UserID in the same way that you currently see ChannelBuyerName for eBay.

For Amazon orders the XML shows both a buyer name and a Shipping Address name.
These are not the same. The buyer name is akin to the ebay userID.
In Linnworks orders from ebay do display both the userID and shipping address name - but in Amazon they only show the Shipping address name.
My request is that Linnworks displays the buyer name from Amazon orders in the ChannelBuyerName field.
