Why Variations are helpful:
Variations help to curate an easier and comprehensive customer experience. If products are variated, all product reviews for a variation family are shown on the product page, it can help to drive glance views, and ensure customers have the right information to make a purchase decision.
Tip: Variation updates can take up to 2 hours to reflect on the product page. When deleting a Child ASIN from a variation, it can take up to 24 hours. If variation updates do not appear on the detail page after that duration, contact seller support.
