I'm currently exploring the capabilities of the WhatsApp Business API for a project I'm working on. I'm wondering if the WhatsApp Business API supports sending messages to WhatsApp groups. I've read through the documentation, but I couldn't find a clear answer on this specific feature.

Could someone who has experience with the WhatsApp Business API clarify whether it supports sending messages to WhatsApp groups? If it does, are there any specific limitations or requirements that I should be aware of?

POST = https://graph.facebook.com/{{Version}}/{{Phone-Number-ID}}/messages Body = {     "messaging_product": "whatsapp",     "recipient_type": "individual",     "to": "{{Recipient-Phone-Number}}",     "type": "document",     "document": {         "link": "https://test.pdf",         "filename": "Test"     } } 

When iOS/Android SDK above v15.1.0 is used, the App on developer dashboard shows the version as "v0.0.0" and shows an error on business dashboard "Your app is out of date. To run your app on iOS 14, update to the latest Facebook SDK for iOS.".
My current SDK is fixed at V17.0.0

Cloud api is giving success on sending whatsapp mesage but message is not received on respective number. I am using a template created by me
