problem showing native popup for email and sms

When I run:

local wasShown = native.showPopup(“email”, options)

on the actual iPhone 5s, I’m getting false returned and nothing shows up on the screen

I can’t find any other complaints on here about this, so I assume it’s a problem with my build-settings.

Can someone point me to the correct docs for this??

Just in case, I am calling this from WITHIN the listener for “addressbook”…

in other words, the person picks the recipient of the email from address book, and then I pop open the email pre-filled for that person

Thanks,
Dewey
