Good day, 

I have successfully integrated with the ManyChat API and can validate and Create subscribers. However sending of WhatsApp messages is not working, Please check my payload and logs below:

From your application logs (supabase/functions/whatsapp-checker):

Subscriber Verification: The subscriber was verified as active using the /fb/subscriber/findByPhone endpoint and returned valid subscriber data with ID 657681435.

Request for Support: I need to understand:

1. Is there an issue with message delivery for this specific subscriber?
2. Are there any additional delivery status webhooks we should monitor?
3. What could cause a successful API response but failed delivery?
