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](https://docs.grovs.io/docs/troubleshooting/deep-link-not-opening-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](https://docs.grovs.io/docs/troubleshooting/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](https://docs.grovs.io/docs/troubleshooting/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](https://docs.grovs.io/docs/troubleshooting/sdk-configuration-issues): the SDK doesn't initialize, links come back `nil`/`null`, or test and production are mixed up.
- [FAQ](https://docs.grovs.io/docs/troubleshooting/faq): platforms, custom domains, MAUs, self-hosting, Expo and more.
