SUMMARY:App warnings and the old knowledge base app ends
DESCRIPTION:Two Shopify dates. Merchants using public apps that missed the expiring-token migration see a warning in the admin (developer changelog, October 27, 2026). The standalone Knowledge Base app is no longer available after this day; stores with more than 1,000 facts in that app need to add the ones they want before then (changelog, October 26, 2026).
