Deep links are meant to take you straight to the right page or screen in an app. When they open the wrong account, they cause confusion and frustration. This guide shows practical steps you can take on both Android and iOS to fix misrouted deep links and keep your accounts in the right place.
Deep links work by directing your phone to a specific part of an app. They rely on the app’s built-in rules, or intent filters, to decide which screen to show. If more than one account exists on the same device, or if another app claims the same link domain, the phone may open the wrong screen or prompt for login again. On a busy day, that mix up can feel like a tech glitch you just can’t shake off. The good news is you can fix it with a few targeted steps.
What you’ll learn in this guide
- How to recognize when a deep link opens the wrong account
- A step by step diagnostic plan you can run on your smartphone
- Android specific fixes that restore proper link routing
- iOS specific fixes that fix universal and deep links
- Best practices to prevent misrouting in the future
Symptoms and why they happen
A misrouted deep link usually shows itself in one of these ways
- The app opens but lands on the wrong account or the login screen for a different account
- You see a login prompt even when you are already signed in on another profile
- A web browser opens first, and after login, you are directed to a different account than the one you expected
- A link from a message, email, or another app consistently points to the wrong account on every tap
These issues happen when the link domain is shared by more than one account or when the app’s routing rules conflict with other apps on the device. It can also occur after an app update or a change in how the domain is handled by the operating system.
Diagnosing the problem: a quick, repeatable test plan
Start with a clean test to pin down the cause. The goal is to confirm whether the issue is tied to the device, the app, or the link itself.
- Check the link on a different device
- If the same link opens the correct account on another phone, the problem is likely on the original device or its settings.
- Try an incognito or guest session
- Open the link in a mode that doesn’t share saved credentials. If the link behaves differently, stored login data is part of the issue.
- Use a different account
- If you have multiple accounts, sign into a known good account in the target app and test the link again. If the link now opens a different account, the problem is tied to account data or routing.
- Look at the “Open with” options
- On devices with multiple apps that can handle the same link, the system may show a chooser. If you can pick the intended app and it still opens the wrong account, the link routing is off.
- Document results
- Note which accounts are affected, which links cause the misrouting, and whether the issue happens with specific domains or paths.
Android fixes: restore reliable app link routing
Android devices rely on App Links and Digital Asset Links to route deep links directly into an app. When these pieces don’t align, misrouting happens. Here are concrete steps to fix the problem.
- Verify the app link configuration in the app
- Developers should confirm that the AndroidManifest.xml declares the correct intent filters for the deep links you use.
- If you’re not the developer, ensure you’re using the official app and not a third party that might handle the same domain.
- Confirm the Digital Asset Links file is correct
- The assetlinks.json file must be served from the app’s domain at https://yourdomain/.well-known/assetlinks.json.
- It should include the correct SHA-256 fingerprint of the app signing key and the package name.
- A misconfigured assetlinks.json can cause the OS to question which app should handle the link.
- Remove default associations and relink
- Go to Settings > Apps & notifications > Default apps (or Open by default) and clear defaults for the affected apps.
- Re-test the deep link; you’ll be prompted to choose the proper app again, which helps reestablish the correct association.
- Clear app data and cache
- In Settings, locate the target app and choose Storage > Clear data and Clear cache.
- Reopen the app and sign back in to rebind the account to the correct routing.
- Reinstall and update
- Uninstall the app, reinstall it from the official store, and update to the latest version.
- Test the deep link again to confirm that the correct account opens.
- Use explicit link paths when possible
- If you control the link format, include a specific path that maps to the exact screen and account. For example, use paths like /account/{id}/overview instead of generic routes.
- If multiple accounts could be implicated, include an account identifier in the URL so the app can resolve the right screen before prompting for login.
- Verify app links are actually verifiable
- Some devices provide a “Verify App Link” option in the settings or developer tools.
- Use this to confirm that the domain is linked correctly to the app and that the OS will not switch to a browser fallback.

iOS fixes: tighten up universal links and app associations
On iPhones and iPads, deep links often rely on universal links and the Associated Domains entitlement. When those pieces don’t line up, the wrong account can surface.
- Check if the app supports universal links
- Universal links connect a domain to an app in a secure way. If the domain is not correctly declared, iOS may fall back to Safari or show a login screen.
- Review Associated Domains in the app
- The app must list the domain in the Associated Domains entitlement. If you’re a user, you won’t change this yourself, but you can report a misrouting to the app’s support team.
- Reinstall and update
- Remove the app, install the latest version, and test again. Updates often fix routing problems introduced by changes in the app’s deep link handling.
- Manage login state and account selection
- If the app shows a login prompt for a different account, sign out of all accounts in the app, then sign back in with the account you want to use.
- In iOS, make sure you allow the app to open links in the app when prompted. Some devices offer a choice like “Open in App” or “Open in Safari”; selecting the right option helps with consistency.
- Consider the browsing option
- iOS users can adjust how links open in Safari or within the app. If a misrouting occurs, forcing the link to open in the app can resolve the issue. Check Settings > Safari > Open Links and set the preferred option to keep links in the app when available.
- Test with multiple accounts and networks
- If your device uses different networks (WiFi vs cellular), test both to rule out network-specific routing issues. Occasionally network-based DNS or security settings influence how a link is handled.
Best practices to prevent misrouting in the future
Preventing misrouted deep links is easier than fixing them after they happen. Here are best practices for both users and developers.
For users
- Keep apps updated and avoid multiple apps that claim the same domain
- Use per-account links when offered by the service
- Periodically clear saved credentials for apps you do not use often
- Use a single device profile for sensitive accounts when possible to reduce cross account confusion
For developers
- Use distinct, well-defined paths for account-specific screens
- Implement an account picker when a link could map to more than one account
- Keep the asset links or AASA file up to date after any domain or signing changes
- Provide a clear fallback that shows a login screen with a prominent option to switch accounts
- Test across common configurations, including devices with multiple accounts and different OS versions
When to seek help
If misrouting persists after trying the fixes above, reach out for support. If you’re a user, contact the app’s customer support and share:
- The exact link you tapped
- The account you expected to see
- The device model and OS version
- Steps you took to reproduce the issue
If you’re a developer or administrator for an organization, review server-side routing rules, confirm the assetlinks.json and AASA files are live, and verify that the app’s sign-in flow can gracefully handle multiple accounts on a single device.
Conclusion
Deep links should simplify access, not complicate it. By diagnosing the source of misrouting and applying targeted fixes on Android and iOS, you can restore smooth, consistent account navigation. Start with a clear test plan, then tackle the specifics of your platform. The right setup reduces friction, improves security, and makes your on device experience much more predictable. If you’ve followed these steps and the problem still shows up, don’t hesitate to escalate with the app’s support team or your organization’s technical contact. A small adjustment now can prevent bigger headaches later.
