Has anyone run into the issue where not all the users are returned? At the moment only users who have contributed to content are returned in the following endpoint. At the moment there should be 15 users returned and only 6 are included in the following request:
http://dev-twg-express.pantheon.io/wp-json/wp/v2/users

Am I missing something?

Have also tried forcing http://dev-twg-express.pantheon.io/wp-json/wp/v2/users?filter[per_page]=-1

Thanks so much for all your help.
