so recently I added my products from Shopify to Google Merchant Center and installed an app called Google on Shopify which tells me that my products are Pending. However, when I go to Google Merchant Center my products appear Active. My question is should I wait for the Google app to show that my products are active or I can still run ads? Here are some photos.
Do not use the app to verify any data, its a very bad app.
Always use Google Merchant Center to verify anything related to Google Merchant Center. The app you are using is 3rd party, which means it is not the source of info, and thus the accuracy can not always be correct.
