My existing app uses Python Social Auth to allow account creation via Facebook, in addition to creating a custom account. I now want to add the ability to collect the user's email address by adding SOCIAL_AUTH_FACEBOOK_SCOPE = ['email']
to my settings file.
But how does this affect existing accounts? If someone has already logged-in with Facebook (meaning they already have an account with my app) when I didn't ask to access their email, what happens now that they come back to the app? Will I be able to get their email?
