I’m running into an issue with the Vercel deployment: • Pushing code to GitHub successfully triggers a new deployment (visible in the Vercel dashboard). • The custom domain still serves the old UI, even after several deploys. • Backend environment variable changes reflect correctly (so deployments are working). • UI code changes do not show up on the custom domain.

Actions Already Taken • Hard refresh and incognito testing → No effect • Query string cache busting (e.g. /index.html?v=2) → No effect • Added Cache-Control: no-store, no-cache, must-revalidate... via vercel.json → Present • Redeployed multiple times with “Clear Build Cache” enabled → No effect • DNS verified and pointing directly to Vercel → Correct • No external CDN or proxy in front (e.g. Cloudflare) → Confirmed • Did not remove/re-add domain (to avoid risk of downtime)

Current vercel.json

          "value": "no-store, no-cache, must-revalidate, proxy-revalidate, max-age=0"

        }

      ]

    }

  ]

}

Summary • Deployments succeed • Custom domain remains stuck on old UI • Env variable updates apply correctly UI code changes not reflecting on custom domain

Currently I don't see any UI changes.
