Hi all,
We have been using the Send Messages API with template buttons at https://graph.facebook.com/v18.0/me/messages.
I received an error with the following details: Code: 100, SubCode: 2018023, fbtraceId: AlJOcqaDk5993l2-k7v0o8o, msg: (#100) Save attachment failure.
The error occurred only for PSID 4822705404446239; the others were successful without errors.
session_id: https://developers.facebook.com/tools/explorer/1621755161178887/?session_id=944758980529968
Any idea or any reported bug as I didn't find any?

I have a test application with a verified webhook and a connected test user in the Meta developers console. The webhook has two subscriptions: messages and messaging_postbacks. The webhook receives the messages callbacks but doesn't receive postbacks when the test user clicks postback buttons in the chat.Could you please tell what is the problem?
In the same time it receives test messaging_postbacks from the developer console.

We are receiving the "User consent is required to access user profile" for users who are directly messaging a business.
As an example, using a webhook for the incoming message:
{
"object": "instagram",
"entry": [
{
"time": 1710698073629,
"id": "17841401619523691",
"messaging": [
{
"sender": {
"id": "7258088794280671"
},
"recipient": {
"id": "17841401619523691"
},
"timestamp": 1710698073342,
"message": {
"mid": "REDACTED",
"text": "Kit"
}
}
]
}
]
}
