Hi,
I’m having an issue with upc upload to my items to google merchant center.
I uploaded my items without upc, and google approved those items.
I entered the upc in shopify but google didn’t update it,
It’s showing in my settings that only product availability and price update automatically.
How do I change that to update
That is an issue if you are using the free google shopping channel. It has been bugged for over a year.
If you want to continue to use that app, then the only solution is to add a supplement feed in Google Merchant Center, with the ID’s and gtin’s

Or instead use an app that works, such as: https://apps.shopify.com/multiple-google-shopping-feeds
