If a Deep link is opened on a device where the app isn’t installed, the system doesn’t just stop there.
Instead, the link automatically redirects to the fallback URL configured for that Deep link. This might be a mobile web page, such as a landing page, product page, or even the app download page. As a result, the flow continues smoothly without leading to a dead end.
This behavior ensures that even without the app, the link still delivers a meaningful destination and keeps the experience consistent.
