Description:
I am working on integrating Facebook account linking for my CRM project. Specifically, I am implementing the following:
OAuth Flows: To authenticate users and obtain access tokens.
Graph API Endpoints: For posting text, images, and videos, including combined multimedia posts, using my C# .NET Core Web API.
Problem:
I am encountering the following error during the OAuth process or API calls:
"It looks like this app isn't available. This app needs at least one supported permission."
Steps I've Taken:
My app is set to Live Mode.
I have verified the App ID, App Secret, and Redirect URI.
Necessary permissions have been added and submitted for review in the App Review section.
Access tokens are generated with the required scopes.
Despite these steps, the issue persists.
Request:
Could anyone help me identify potential reasons for this issue and suggest resolutions? I’d also like guidance on confirming whether all permissions are correctly approved and whether additional steps are needed for production use.
Thank you in advance for your assistance!

I can't seem to moderate the Facebook Comments for my site. Anyone able to tell me the problem? FB says they no longer give support for the FB Comments Moderation Tool. :-(

Any attempt to moderate ends with:
"This content is no longer available The content you requested cannot be displayed right now. It may be temporarily unavailable, the link you clicked on may have expired, or you may not have permission to view this page."

Hi support,
Before we started receiving JSon with a following node in the return
entry[1].changes[1].value.messages[1].document.id
and now only the Json is coming up to the entry[1].changes[1].value.messages[1].document tag
We need our customers to view images and documents, but the json is not being returned in full

WhatsApp API is not sending in the request the image sent by users.

Hi, a few days ago I was receiving messages correctly with attachments or contexts. But I'm trying today and I'm not receiving the complete json.
Here is the documentation, which says that nothing has changed:
I need help, I don't know if it's because of something in the code, configuration or payment on the account.
