How to troubleshoot the wrong app or web fallback

The wrong app or content opens

• Open the final web destination and confirm it points to the exact public content you expect.
• Check country routing first; app routing uses the final routed destination.
• Use automatic mode for a recognized provider unless you have a verified reason for a custom app URL.
• Remove extra shorteners or redirects that hide the final provider URL.
• If using custom mode, confirm the app URL format is valid for the intended app and device.

Only the web fallback opens

• Confirm app routing and deep linking are enabled for the Smart Link.
• Confirm the current device is enabled.
• Check whether LinkStack recognizes the final provider and URL shape.
• Confirm the destination app is installed and allowed to open links.
• Check the Instagram or TikTok switch when testing inside those apps.
• Desktop traffic is expected to use the web destination.

The fallback uses the wrong browser

• Review the app-not-installed fallback for the current device.
• Choose external browser when you want to leave a social in-app browser.
• Choose in-app browser when you intentionally want to stay inside the social app.
• Use the account default or save a device-specific override, then retest the public link.

Retest cleanly

1. 1Save every routing section you changed.
2. 2Open the public Smart Link in a new browser session.
3. 3Test the installed-app and fallback cases separately.
4. 4Record the device, browser, destination, and result before changing another setting.
