Google has acknowledged reports that reinstalling the Google & YouTube Shopify app before the August 18, 2026 migration deadline may change product IDs in Google Merchant Center. This is related to the transition from the Content API to the Merchant API.
If product IDs are rewritten, advertisers lose historical product performance data, which negatively affect Google Ads reporting and campaign optimization.
Google Ads Liaison Ginny Marvin has responded on Matinique Roelse’s LinkedIn post confirming the team is investigating the issue, but no fix has been announced yet.
