Currently, before 30 days elapses I need to go in to Inventory->Volusion API->Google Shopping Feed

and click the 'generate xml' and 'publish to google' buttons manually. If I don't do this, all of my products fall off of the merchant feed, and as a result out of availability for adwords advertising.

I'm not sure what forcing us to do this manually accomplishes. Seems completely like something that could be automated. I haven't found a way though. Anyone else?
