| N/A | The Cortex XDR agent app for iOS is not available when the Apple App Store is accessed from the People's Republic of China. |
| Network Shield module | Automatic registration, facilitated by providing the `distributionID` in the payload configuration profile for network filtering, is only supported in iOS version 17 or higher. |
| Safari Safeguard module | For Cortex XDR apps earlier than version 8.5.0, an issue in iOS versions 17.4 and higher causes the Cortex XDR agent's Safari Safeguard module, and anything based on Safari Web Extensions, to stop working after a short period of time. Apple has confirmed the issue, but a complete fix resolving the issue has not been released yet.
Cortex XDR 8.5.0 includes a fix with a workaround for the issue that Apple introduced in iOS 17.4. With this fix, Safari Safeguard is now expected to work on all supported iOS versions.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
