I am currently developing an iOS app which is integrated with Facebook SDK for inviting users to use the app. The iOS app is not on the apple store since it's under development (obviously). However, when I use a test user to invite Facebook friends, no-one of his test friends receive a Facebook notification about it.
This is what I've done on Facebook: I have created an test app and created an app link with Facebook's tool. I created test users for my test app.
This is the workflow with my iOS app: I have a Facebook login button in my app. When a user logs in, there's a button to invite friends. When user clicks on it, it opens the Facebook invite dialog. User can select friends and invite them. Everything seems to work on that end (no errors whatsoever).
Anybody has an idea of what's wrong with my setup?
Thanks, J
