question:

i have tried run app new user: 1. when press login button, process , pop "user signed , logged in through facebook!" however, after logged in, turns userdetails page, reports via toast "no profile!" , ie currentuser has no info inside. going wrong here?

  1. why there no permission page popup when login despite got "email" permission?

thanks lot!
