I am integrating my facebook business account in my auth0 tenant. Auth0 Tenant is integrated to my project successfuly. But when I click on continue with facebook, it redirects me to facebook loginpage and after authenticating me it says ‘App is not Available’.

Hi @abubakarzorrain

Welcome to the Auth0 Community!

It looks like you encountered an issue with the Facebook integration. Can you share more details or logs from the Facebook side? I would also encourage you to contact Facebook business support directly → Facebook Advertising Support | Meta Business Help Center

Thanks
