Updated permission settings bring enhanced security to your B2B store pages. In the Starter, Pro Suite, and Freemium editions, after you upgrade to Winter '27, B2B Commerce users without the Commerce Admin permission will no longer have access to store pages. Assign the Commerce Admin permission set to restore their access.
Where: This change applies to B2B Commerce in Starter, Pro Suite, and Freemium editions. Enterprise, Unlimited, and Developer editions aren't affected.
