I am experiencing an issue with my app (App ID: 976657567571568). The Facebook Login feature is currently unavailable, and I am receiving the following error message: "Feature Unavailable: Facebook Login is currently unavailable for this app, since we are updating additional details for this app. Please try again later."

I have ensured that all required details, including Privacy Policy URL, Terms of Service URL, and Data Deletion Request URL, are correctly filled out and publicly accessible. I have also checked that there are no pending app reviews or policy violations.

Could you please provide more information on why this feature is unavailable and any steps I need to take to resolve this issue?
