Can’t log into the Facebook App

Got locked out of Facebook on my iPhone. Tried to log back in. Facebook wouldn’t accept the password. Tried to change the password. Facebook wanted photo ID. Sent that off with no answer after 6 days. After another attempt tonight, and signing in thru google, got a txt from Facebook, that I was logged in. But I still can’t access Facebook through the app. It keeps saying the password is incorrect, so tried changing it again, they wanted photo ID again. Sent that off again. So please if anyone has any suggestions how to fix this, I would appreciate any help to get it sorted. So frustrating. Thanks in advance. 😊
