I recently linked my Shopify Account with my Google Merchant Center and exported all of my items into the Google Merchant Center account, and it worked!
So I am glad to say I do not need help with that..Yay!
Now since that initial feed I have added NEW products to my shopify store, but I do not see them syncing to the Google Merchant Center.
Any idea on what I am doing wrong? I plan to add new items weekly so this is an important feature for me.
In some apps you need to manually allow them in the feed, while others its automated. Get in touch with the app support team you use, to know what to do.
