I hope this helps. Thank you.

The "UnsupportedFeature" error in Face API, despite approval, can occur for a few reasons. Here’s how you can troubleshoot and resolve it:

Verify Region:

• Ensure your Face API endpoint and resource region match the region where approval was granted.
  • The Face API may only work in specific regions approved for use.
  API Version:

  - Check if you are using the **correct API version** in your request. Outdated or unsupported versions can trigger this error.
  
  **Subscription Key**:
  
     - Confirm you are using the **correct subscription key** associated with your approved Face API resource.
  
     **Approval Delay**:
  
        - Sometimes, there can be a delay in Microsoft propagating the approval. Verify the approval status in the **Azure portal** under "Cognitive Services" > "Face API."
  
        **Request Quotas**:
  
           - Check your **resource quotas and limits** to ensure you haven’t exceeded any usage caps.
  
           **Endpoint Validation**:
  
              - Double-check the **endpoint URL** in your request. The correct format should look like:
  
              ```
