Business Login for Instagram is not working for mentions as noted here: https://developers.facebook.com/docs/instagram-platform/instagram-api-with-instagram-login/mentions

Problem: I’m using the Meta WhatsApp Business API to send template messages. When I try to send the first message using Postman, I get a 200 OK response, but the message is not delivered to the recipient's phone. However, if the user sends me a message first, the API works as expected, and the message is delivered.

Here is the JSON request I'm using:

{   "messaging_product": "whatsapp",   "to": "91790******",   "type": "template",   "template": {     "name": "hello_world",     "language": {       "code": "en_US"     }   } } 

The response I receive is:

{   "messaging_product": "whatsapp",   "contacts": [     {       "input": "91790******",       "wa_id": "91790******"     }   ],   "messages": [     {       "id": "wamid.HBgMOTE3OTA0NjMwMzM3F***dfdffQkI1QzcwNTd**==",       "message_status": "accepted"     }   ] } 

I’ve confirmed that the template (hello_world) is approved and active. The API request returns a 200 OK response, but the message is still not delivered to the recipient unless they initiate the conversation by sending a message first.

Question: Why is the message not being delivered when sending it as the first message? How can I send the first template message without requiring the user to send a message first?

Additional Details: I’m using the Meta WhatsApp Business API. The template is approved, and the recipient's phone number is valid.

Sending of message failed. Unsupported post request. Object with ID '448049831720158' does not exist, cannot be loaded due to missing permissions, or does not support this operation. Please read the Graph API documentation at https://developers.facebook.com/docs/graph-api

Hello,
We're trying to migrate our App from using the old "Instagram API setup with Facebook Login" to the new "Instagram API setup with Instagram Login"
Reading the official migration guide: https://developers.facebook.com/docs/instagram-platform/instagram-api-with-instagram-login/create-a-meta-app-with-instagram
It says to add the "Instagram" product, however there's no such product we can add. We already have "Instagram Graph API" and "Instagram Basic Display" but there's no "Instagram".
We assume the issue is that the app must be of type "Business", while our app is of type "none" since it was created before apps were categorized.
Is there any way to migrate our existing app from "none" to "business" or to get the Instagram product available?

I wanted to know if someone can give me a hand. Until today I was using touch.facebook.com in Mozilla Firefox version 48, but it is no longer available.

So far I have tried in these versions:

In these it tells me that “browser is not supported”. 49.0.1 48.0.2 48.0.1 48.0 47.0 43.0b9 37.0 1.5.0.3 33.0

And in these directly redirects to facebook.com 69.0b9 58.0

I also tried in the last available version of Safari for Windows, but it is so obsolete that the Login button does not work.

I couldn't get it to work in older versions of Chrome or Internet Explorer either.

Anyway, if anyone still knows how to login to touch.facebook.com either from mobile or from pc, I will be very grateful.
