I accidentally logged out of my Facebook app and can no longer log in . It says "Login Failed" Sorry, an unexpected error occurred. Please try again later. Error code: 100. (I have an iPhone X)

I can log in to Facebook if I do it through the browser on my phone and I can log in on my macbook as well.

I have tried turning my phone off and then on again, I have deleted the FB app and reinstalled it. I changed my password. Nothing is working. I went into settings, then the Facebook app and I don't see anything in there that will help the situation.

Of course it is impossible to contact anyone at Facebook for help. Does anyone in here have any ideas?

Why is my Facebook app not working on my phone?

How do I log back into my Facebook app?

Why does my Facebook app keep saying login error on iPhone?
