Hello Jsow102 -
Our engineers are aware of the issue you refer to with shipping method information, however we have confirmed that we are sending the data as it has been recorded in the Saved Listings. We are looking into the issue and hope to have it resolved soon.
As for using Business Policies from within your Auctiva account, we do have a Beta version of our lister page that makes use of eBay's business policies from within your Auctiva account. If you have such set up on eBay and wish to make use of that version of the lister page, please file a support case letting us know and we can set your account up to be a part of that Beta. The page will allow you to select from your available eBay Business Policies while creating a listing and then post to eBay making use of those policies.
