How to quickly resolve bulk product update issues on sales channels?

1 0 0

I manage a Shopify store that has over 9,000 products that was suspended on Google for data issues. I made a bulk change to remove all products from the Google Channel, and it instead did the opposite - unpublished from all channels except Google. I am trying to find a way to revert each product to it's original, or find a way to restore from this morning before the change occurred but unfortunately not having any luck with the support side.

This store uses Shopify POS so this is affecting their in-store sales system right now.

Any suggestions on how to resolve this quickly? I did another bulk change to enable it across all sales channels now, but ideally, I could just restore it to what it was...
