OK fair enough 
I’m also finding my beta users are signing up and filling in the custom fields that I’ve created, as they get shown them on sign-up, but I’m struggling to get them to fill in the standard profile fields, such as location, or to get them to upload a profile image.
It would be great to be able to choose what standard profile fields to present new users with in the sign-up form, along with the option of asking them to upload a profile image - I think this would drive much greater profile completion.
