DeprecationUnverifiedAdded Sep 24, 2026
Shopify will stop setting the shopify_y and shopify_s cookies in 2026. If you use these cookies, your storefront will continue to work normally. However, if you don’t upgrade, visitor and session attribution won't be reliable in in Shopify Analytics. For Hydrogen storefronts, upgrade by April 30, 2026.
