# Why Is My Test Showing Attribution to the Wrong Campaign?

> Fix the common issue where test installs or signups get attributed to a previously tested campaign link instead of the new one

## The Problem

You click a new campaign link and test a signup, but the dashboard attributes it to a **different campaign** — usually an older test link with a stale date.

## Why This Happens

The SDK generates a unique **install instance ID** on first launch and persists it on the device. All subsequent activity (installs, signups, events) is tied to this ID. When you test again **without uninstalling**, the SDK reuses the same ID and the backend attributes everything to the original campaign.

**No uninstall = same ID = attribution stuck on the first campaign.**

## How to Fix It

### 1. Uninstall the app before each test

This clears the stored install instance ID so a fresh one is generated on next launch.

<Warning>
  Force-stopping the app is **not enough** — you must fully uninstall it.
</Warning>

### 2. Enable debug mode

Set `debug = true` in your SDK init to see logs confirming a fresh install.

<Tabs>
  <Tab title="React Native">
    ```javascript theme={null}
    await linkrunner.init("TOKEN", "SECRET", "KEY_ID", false, true);
    ```
  </Tab>

  <Tab title="Flutter">
    ```dart theme={null}
    await LinkRunner().init('TOKEN', 'SECRET', 'KEY_ID', false, true);
    ```
  </Tab>

  <Tab title="iOS">
    ```swift theme={null}
    await LinkrunnerSDK.shared.initialize(
        token: "TOKEN", secretKey: "SECRET", keyId: "KEY_ID",
        disableIdfa: false, debug: true
    )
    ```
  </Tab>

  <Tab title="Android">
    ```kotlin theme={null}
    LinkRunner.getInstance().init(
        context = applicationContext, token = "TOKEN",
        secretKey = "SECRET", keyId = "KEY_ID", debug = true
    )
    ```
  </Tab>
</Tabs>

### 3. Run the test flow

1. **Click** your new campaign link on the test device
2. **Install** and **open** the app within 3 minutes of clicking
3. **Signup** (if testing signup attribution)

<Tip>
  **Multiple tests?** Uninstall between each run for clean attribution.
</Tip>

## Still seeing issues?

* Confirm you clicked the link **on the same device** where the app is installed
* Confirm you opened the app **within 3 minutes** of clicking
* See the full [Integration Testing guide](/testing/integration-testing) for a detailed walkthrough
