Problems with Facebook login

(Swift)
Hi everyone!
We are having problems in our application in production, what happens is that when trying to log in via Facebook, while the Facebook application is installed, it stays in an infinite loop and we have not found the solution. Attached is a picture of the problem (the loop)
It is a problem that only occurs if the Facebook application is installed on the user’s phone.

What do you mean by loop? I can’t see it in the screenshot.
