I am using Facebook login to grab user data for a contest promo. The user is linked to my promo page on my domain from a Facebook Ad. Once the user is there they click the facebook button to populate First Name, Last Name, and Email. I can get everything except the email and I can't figure out why. It actually works for my Facebook account(maybe because I am a developer) but not for anybody else that has tried it. Any ideas why this isn't working?
this may be because of the users privacy setting, and as you know users can choose between TO and NO TO show the email's, try with your another account with different privacy setting.
