Hi guys, I've got a new Meta app, not yet reviewed by Facebook and I wanted to test my webhook with live messages but it seems that I cannot get any update from Facebook. I've been able to set the webhook in the Webhooks section and I can receive the test payload but when I send a message from a real number nothing happens. The WABA has finished the embedded signup process, I've generated the Business Integration System User access token using the code from embedded signup, I've registered the number from the WABA and then I've made a POST request to /subscribed_apps to subscribe to webhook notifications. The part that I find weird is that the conversation and the received and sent messages appear in the WhatsApp dashboard. Can any of you share your insight on this? Am I not receiving webhook notifications because the app hasn't passed app review?

Thanks!
