I currently have my app in google play apha testing mode. On Facebook, it is also in development mode while I'm waiting for the game to be reviewed and approved. I'm using PlayFabClientApi.GetFriendsList() to get friends data after I've logged in with Facebook. I'm calling this method twice (the second call happens in the result callback method of the first call) because of the bug with setting the 'ProfileConstraints' that has existed forever and you still haven't fixed. This works normally on all phones I've tested it on, except one. On that one, belonging to a friend, I'm getting an exception in code after connecting to Facebook and trying to get the friends list. After this happens, I'm getting the internal server error whenever I open the friends section of his profile in the manager. Adding friends manually also does not work. It just reports an error with no explanation. Since this works on all other devices I've tested it on, belonging to different people, I was wondering if you could tell me what could be the cause of this? Could his Facebook account somehow be blocking PlayFab from getting the friend info?
