...But this is what it needs to be reviewed for.
My Messenger app approval keeps being rejected with this:
pages_messaging This item was not approved. Click Edit Details for information.
Facebook then states that the app does not respond when messaged - however, Facebook appears to be testing the app using a non-tester profile, which the system cannot respond to because that's what it needs approval to be able to do in the first place.
They also provide a screenshot of the messages sent, but these never show up in our page's Messenger inbox or in our database.
Facebook has also tested using tester profiles, but the app has always responded to them. The app also obviously responds to myself, the admin and my own test profiles.
Am I missing something? Why would Facebook review my app for public use, whilst using a non-tester profile?
