Locked Out

Back when 2FA started we didn’t need a QR code and then one day it changed but I couldn’t do anything about it because I couldn’t get in and I couldn’t cancel it because I couldn’t get it. I thought, oh it’s fine, I can still get into my account. That happened until an update logged me out and now I can’t get back in because I couldn’t set up the new 2FA and cancel the old one because I couldn’t get into that one
