Error while logging on to Facebook messanger

Hello there,

The issue seems to be with the Facebook application. That app has not been developed from apple therefor I would recommend you to get in touch with facebook in this case.

You can check this article https://support.apple.com/en-al/HT207959 for some tips on how to contact an app developer.

Good luck!

If you cannot log into the app, then you need to contact Facebook for support. This would be either for your account or for their app.

and after click , app support what should i do? its little bit weird to txt support about my problem
