Fix Google Merchant Disapprovals

My Shopify product feed has been flagged in Google Merchant Center. Every item is currently disapproved because Google says the product identifiers are invalid. The only attribute causing trouble right now is “Brand.”

Here’s what I need:

• Audit the existing Shopify-to-Merchant Center feed and pinpoint exactly why the Brand attribute is failing.
• Update or map the correct Brand values (or create a reliable rule) for every product.
• Resubmit the feed and monitor until the disapproved products are fully approved.
• Provide a brief hand-off note so I can keep the feed compliant going forward.

If you have proven experience fixing invalid product identifiers in Google Merchant—especially within a Shopify setup—let’s get this resolved quickly.
