- Near real-time detection frequency isn't available for detections that include Microsoft Sentinel data.
- Custom functions that were created and saved in Microsoft Sentinel aren't supported.
- Defining entities from Sentinel data isn't yet supported in custom detections.
- When creating a new Microsoft Sentinel function in Log Analytics, there is a delay of up to 20 minutes until it appears in Advanced Hunting.
- Bookmarks aren't supported in the advanced hunting experience. They're supported in the **Microsoft Sentinel > Threat management > Hunting** feature. Alternatively, you can use the [Link to incident](advanced-hunting-defender-results.md#link-query-results-to-an-incident) feature to link query results to new or existing incidents.
- If you're streaming Defender XDR tables to Log Analytics, there might be a difference between the`Timestamp` and `TimeGenerated` columns. In case the data arrives to Log Analytics after 48 hours, it's being overridden upon ingestion to `now()`. Therefore, to get the actual time the event happened, we recommend relying on the `Timestamp` column.
- When prompting [Security Copilot](advanced-hunting-security-copilot.md) for advanced hunting queries, you might find that not all Microsoft Sentinel tables are currently supported. However, support for these tables can be expected in the future.
