Setting the correct runtime language is important because:

* It improves accessibility compliance for multilingual users.
* It reduces browser translation interruptions.

## Tips

1. Each app should be designed in a **single language**. The Runtime Language setting applies to the entire page and does not support per-control or mixed-language configurations.
2. If you still encounter browser translation prompts, you can disable them by selecting the option **Never translate this site** in the browser settings.
3. Runtime language and selected Preferences Language should be kept same to avoid any issues.
