I lost, forgot, or deleted the app, and reinstalled it because I changed my phone. But I can't find the QR code for Facebook authentication. I contacted Facebook, but they couldn't help me and asked me to contact you. It’s possible that I didn't register with an email, or maybe I did; I can't remember exactly, regarding my Facebook app
