# Troubleshooting

Here are some common issues and their solutions:

| Issue                    | Solution                                                                                   |
| ------------------------ | ------------------------------------------------------------------------------------------ |
| SDK initialization fails | Check your internet connection and ensure you have the correct API keys                    |
| Ads not loading          | Verify that your placement IDs are correct and that your app has the necessary permissions |
| Poor ad fill rate        | Consider adjusting your targeting parameters or try different ad formats                   |

### Best Practices

* Initialize the SDK as early as possible in your app's lifecycle
* Cache ads in advance for a smoother user experience
* Implement multiple ad formats to maximize revenue
* Test ads in development mode before releasing your app
* Monitor ad performance regularly and make adjustments as needed
