March 2026 focused on stabilizing the B2B buyer portal shopping workflow by addressing a race-condition that prevented logged-in users from adding products to shopping lists. A targeted fix gated the Add-to-Shopping-List handler on the page initialization after the Redux store reflects the current user role, ensuring logged-in users (role 1) can add items without triggering the guest prompt. The change was implemented in apps/storefront/src/hooks/dom/useOpenPDP.ts with a guard on isPageComplete and a dependency-driven reattachment of the handler, and committed as f400848baa1068db8a5581d4fc0432a8e6c03ebf (B2B-4462). The rollout note indicated a rollback of the PR to maintain stability; no database or config changes were required. The work was validated through manual end-to-end testing in the B2B flow to confirm logged-in users can add items and do not see the guest modal. Plan to re-ship after additional validation.
