 * **Exponential back-off with jitter**: This default retry policy tends to be aggressive at the start and slow down over time until it reaches a maximum delay. The design is based on [Retry guidance from Azure Architecture Center](https://docs.microsoft.com/azure/architecture/best-practices/retry-service-specific). 
 
-* **Custom retry**: For some SDK languages, you can design a custom retry policy that is better suited for your scenario and then inject it into the RetryPolicy. Custom retry isn't available on the C SDK.
+* **Custom retry**: For some SDK languages, you can design a custom retry policy that is better suited for your scenario and then inject it into the RetryPolicy. Custom retry isn't available on the C SDK, and it is not currently supported on the Python SDK. The Python SDK reconnects as-needed.
 
 * **No retry**: You can set retry policy to "no retry," which disables the retry logic. The SDK tries to connect once and send a message once, assuming the connection is established. This policy is typically used in scenarios with bandwidth or cost concerns. If you choose this option, messages that fail to send are lost and can't be recovered.
