I've created an app that requires showing the user a list of his groups on Facebook. I'm asking for the user_groups permission and all is working fine in development.
I submitted the app for review in order to make it live and my user_groups permission request was unapproved with the following message:
The user_groups permission is only approved for apps that let people use Facebook on platforms where Facebook is not already available. If you're building an app on Android and iOS, for example, you won't be approved for this permission. Web, Desktop and TV apps will also not be granted this permission.
I just had to make sure I understand: Are no Android, iOS, or Web apps allowed to use this permission?? This sounds strange... Am I missing something?
