</Accordion>

## Testing compatibility

<Steps>
  <Step title="Verify browser version">
    Check you're using a supported browser version:

    1. **Chrome/Edge**: `chrome://version` or `edge://version`
    2. **Firefox**: `about:support`
    3. **Safari**: Safari → About Safari
    4. **Brave**: `brave://version`
  </Step>

  <Step title="Test in incognito/private mode">
    This tests without extensions or cached data:

    * **Chrome**: Ctrl+Shift+N (Cmd+Shift+N)
    * **Firefox**: Ctrl+Shift+P (Cmd+Shift+P)
    * **Safari**: File → New Private Window
    * **Edge**: Ctrl+Shift+N (Cmd+Shift+N)

    <Info>
      If ZeroTwo works in private mode but not regular mode, the issue is likely caused by an extension or cached data.
    </Info>
  </Step>

  <Step title="Try different browser">
    Test with a completely different browser to isolate browser-specific issues:

    1. Install alternative browser if needed
    2. Navigate to zerotwo.ai
    3. Log in and test functionality
    4. Compare behavior to primary browser
  </Step>

  <Step title="Update system and drivers">
    Ensure your system is fully updated:

    * **Windows**: Windows Update
    * **macOS**: Software Update
    * **Linux**: Package manager updates
    * **Graphics drivers**: Manufacturer website

    <Warning>
      Outdated graphics drivers can cause rendering issues and poor performance even with an updated browser.
    </Warning>
  </Step>
