Hello.
Emoji's that are transmitted via the API are not displayed correctly on Facebook. This functionality worked correctly. But now instead of emoji's the symbols "?" are displayed. When I edit the title from the Facebook side, the emoji's are displayed correctly. But when emoji's are passed through the API, the emotions are not displayed. UNICODE is used to transmit emoji's via the API.

Hi,
I would like to test the Threads API. First, I discovered it was not possible to add the Threads API access to an existing app... so I created a new one with the use case Threads. But 2 apps were created with the same name: one with Threads access and another one without Threads access. For the first one, I am not able to test anything in the Graph Explorer Tool because when I click on "generate access token" I get the error "Facebook Login is currently unavailable for this app, since we are updating additional details for this app. Please try again later." as you can see in the enclosed screenshot.
What can I do to test it please?
Thanks in advance!
