Yes. In Amazon’s announcement about review sharing across product variations, the company says reviews will be re-shared for eligible products if sellers update their variation themes after the review-sharing change takes effect.
What does Amazon actually say?
Amazon says in the announcement that if sellers need to update variation themes after the change takes effect, reviews will be re-shared for eligible products.
The important qualifier is eligibility. Amazon is not promising that every variation family will regain shared reviews after an update.
What makes a product eligible?
Based on Amazon’s announcement, eligibility depends on whether the variation relationship fits the kinds of minor, non-functional differences Amazon still allows for shared reviews.
If the relationship still groups together materially different products, sellers should not assume review sharing will return.
Why might a seller need to update a variation theme?
Amazon recommends in the announcement that sellers review variation setup to make sure the variation theme matches the real product difference.
Its example is straightforward: use a color variation for a color difference, not a quantity difference.
What should sellers take away from this?
The announcement suggests that variation cleanup still matters after the rollout begins.
If a variation family is updated to match Amazon’s eligibility rules more closely, review sharing may be restored for the products that qualify.
