Troubleshooting

Find the page that matches your symptom. Each one gives the cause, how to confirm it, and the fix.

• Deep link doesn't open the app: links open the browser instead of your app. Universal Links, App Links, fingerprints, and the native config behind Flutter and React Native.
• iOS setup checklist: check dashboard values, Associated Domains, URL schemes and SDK logs in order, then test every flow before you ship.
• Deferred deep linking: the link was tapped before install and the payload never arrives, usually because of how the flow was tested.
• SDK configuration issues: the SDK doesn't initialize, links come back nil/null, or test and production are mixed up.
• FAQ: platforms, custom domains, MAUs, self-hosting, Expo and more.
