I have a question about the Instagram webhook. I'm experiencing the following problem with webhook “messaging_seen” requests, Is this a specification?
(1) Multiple messages are unread. 　(*Messages were sent at different times. 2) When I open a DM thread, a request for “messaging_seen” is sent via webhook. 　　The request is sent as many times as the number of unread messages. (3) Check the contents of the request and you will see that the mid is the same value for all the messages. 　Is it the mid of the latest message?
Question: When a “messaging_seen” request is sent by webhook, is the specification that the mid in the request is the mid of the latest message among unread messages?
Remarks: https://developers.facebook.com/docs/graph-api/webhooks/reference/instagram/#messaging_seen Although not specifically mentioned in the reference, there is a description like “”mid“: ‘last_message_id_read’” in the TEST for webhook in the Meta app.
Thanks again for all your support.

The expected behavior was to not display anything at all just like the ios version. This only happens in Android. We found this issue putting together multiple checkboxes and radio buttons in a screen and changing the visible property.
You can watch this problem in multiple wabas but i send you the one we use for deveploment: WABA ID: 131678500028062 Flow ID: 1634209397219994
You can test the problem using the checkbox or radio button example at the documentation with the next json flow.
When visible is false for the checkbox component it takes some space of the flow. This should not happen and should work like the ios version.

There was a problem registering [...]. Unsupported post request. Object with ID '520361677835099' 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

I'm trying to enable the custom flow described in the documentation: https://developers.facebook.com/docs/whatsapp/embedded-signup/custom-flows/onboarding-business-app-users.
I followed all the steps as described in the documentation, but the WABA selection screen has not been replaced with a screen that allows connecting an existing WhatsApp Business account. Any help?

I have been unable to stream on two different Facebook pages simultaneously via RTMP for the past few weeks. Only one stream works at a time, while the second one doesn’t start. This issue didn’t exist before.
I am using Vimeo Live Streaming, and I am also facing the same problem on StreamYard.
