We have been whitelisted for requesting email from users, we’ve enabled the ‘request email’ permission for the app, and we’re making the request properly, according to the documentation: https://api.twitter.com/1.1/account/verify_credentials.json?skip_status=1&include_email=1
The issue is that the email isn’t being returned, even though the permission is granted (and visible in the Settings/Apps list). I’ve tried with existing accounts, and with a brand new account (after verifying the email), as seen here;

This is the entirety of what’s being returned by verify_credentials:
array (
'id' => 710562945793527808,
'id_str' => '710562945793527808',

'default_profile' => true,

At this point, I don’t even know what the field is supposed to be named… is it just ‘email’?
