Facebook App: Login Error; an unexpected error occurred.

So I just made a new facebook account for work and the app is not allowing me to sign in. Note, this is a brand new iPhone XS Max and has not been signed into another account. Some things that I have tried already are:

• Restarting the phone multiple times
• Deleting and reinstalling the app
• Reset my network settings
• Rest all Settings
• Force Reboot the phone
• Everything is updated to the latest software

No matter what I do I keep getting the same error over and over again. Any insight would be great. Thank you.
