Hi I trying to set up our Google Shopping App, and apparently our shopping campaign work fine in google, and our store meets the basic requirements of the Google Merchant Center says the Google Shopping App. How ever the Google Shopping App says that our Product Status is: 0 products are available for the Google Shopping app Approved 0 products During treatment 0 products Not approved 0 products Why does it do that? Do i need to setup a Content API key in Google merchant, and where do i find that key in shopify?
