Deep links are designed to work across major mobile platforms, including iOS and Android. However, their behavior depends on how the target mobile app is configured on each platform.
For Deep links to open correctly inside an app, the app itself must support Deep linking and be properly set up to handle incoming links. This typically involves platform-specific configurations, such as Universal Links on iOS and App Links on Android.
If everything is configured correctly, the Deep link will open the intended screen within the app. If not, or if the app is not installed, the link will fall back to the specified fallback URL (for mobile devices), ensuring that the destination remains accessible.
