At the moment, Cobiro can only work with the initial product feed that you upload during the setup process. Whenever you add a new product to your online store, you need to log into your AdWords account and add this product manually to your campaign. Otherwise, Cobiro can't optimize the bids for this particular product. The same applies to a product that you delete from your product feed because it's out of stock. You need to manually remove the ad related to the specific product in AdWords or it will get disapproved by Google due to a policy violation ("404 Not Found").Please be aware that too many policy violations in your Google AdWords account can lead to account suspension. If you want Cobiro to fetch your whole product feed with the latest product updates, you can also reset your AdWords account from your Cobiro Dashboard. Read more about how to perform a reset here.
