I have been using this app for over 10 years without any major issues. But after a factory reset, I can no longer login. The screen shows either login with Google or Facebook. Either way it still shows "login failed"

I can't even open the app. Both Facebook and Google login give the error "sing up fail". Yes, it spells it "sing".
