Universal links keep sending people to the App Store even when they have the app installed
Users who already have our iOS app tap a campaign link and get the App Store page instead. Android works fine. Any idea what usually causes this?
Answer from the Linkrunner team
The store page is the symptom: iOS did not treat the tap as a universal link, so the tracked link fell back to the store. Check these in order. Paste the link into Notes and long-press it; if an option to open in your app appears, the setup works (typing the URL into Safari's address bar never opens the app). The apple-app-site-association file must load from /.well-known/ on the exact link domain with no redirects, and the app needs an applinks: entry for every link domain. Look for a shortener or email click-wrapper in front of the link. Confirm the app passes the URL to the SDK's deep link handler on cold and warm start. Finally, a user who once chose the browser, a tap from a page on the same domain, or an in-app browser all keep the tap out of the app. The longer iOS failure guide: https://linkrunner.io/blog/why-your-deep-links-break-on-ios-and-how-to-fix-every-failure-mode
