Project snapshots, launches, and behind-the-scenes — follow us on Instagram. The grid needs a valid Meta long-lived token (INSTAGRAM_ACCESS_TOKEN on Vercel). Tokens expire about every 60 days — generate a new long-lived token in Meta, update the env var, and redeploy. Business/Creator accounts often also need INSTAGRAM_GRAPH_BASE_URL=https://graph.facebook.com and INSTAGRAM_USER_ID (numeric). Check Vercel → Deployment → Logs for lines starting with [instagram-feed].
