Webhook Events Not Received for Production Number Despite Active and Verified App

Hello,
I am encountering an issue with my app despite it being active and fully verified for production use:
Context:
The app is active and verified for production according to the documentation. My webhook is configured and successfully receives events for the Test Number. However, for my Production Number, no events are received in my backend. Flow Issue:
I configured the endpoint to handle responses for the "on-click-action" in flows. The public certificate was created, but the status check fails. Could you please assist in identifying why the webhook works for the test number but not for the production number, and why the flow configuration fails the state check?
Thank you for your support.
