I am looking for guidance as to how I am supposed to resolve the required July 1st change regarding the fulfilllment_service field on the ProductVariant resource. I was under the assumption that I simply had to stop using it, and instead use the inventory_item_id to assign a location and manage inventory. It seems this is incorrect, as my app got unlisted for continued use of the fulfillment_service field.
The code that may be flagging my app is a POST to the products endpoint. However, we are no longer populating the fulfillment_service field.
The process also does a GET call retrieve individual variants without specifying API version in the endpoint. Could the lack of a specified API version be the issue? Thanks.
