Reproduce
Record platform, OS, app version, browser, install state and exact URL. Test existing app and fresh install separately.

Deep-link diagnostics
When a link appears broken, the quickest fix usually begins with a precise account of where the journey diverges.
This is an illustrative approach based on my experience. It contains no named client, measured result or confidential material.

THE APPROACH
A structured path through the problem
Trace
Inspect the redirect chain, link parameters, app association configuration and in-app route handling. Compare expected and observed paths.
WORKING OUTPUT · Redirect and route traceIsolate
Check whether the failure sits in link construction, universal/app links, deferred deep linking, SDK configuration or app navigation logic.
WORKING OUTPUT · Evidence-backed hypothesisVerify
Retest the corrected path across relevant devices and install states, then confirm attribution and destination independently.

The first questions I ask
A short evidence request can narrow the problem before engineering spends time on a fix.
- Does the same URL fail on iOS and Android, or only one platform?
- Does the issue appear with the app installed, after install, or both?
- What is the exact final URL and the destination the campaign intended?
- Is the app receiving the link payload but ignoring the route?
- Are test and production settings being mixed?
THE TAKEAWAY
The handover is a reproducible issue with an owner and a verification path, not a vague report that ‘deep links don’t work.’
