When I call https://api.foursquare.com/v2/users/USER_ID/request it returns the object user, but the friend request is not made properly.
For instance: On behalf of a userA the app calls ".../users/userB_ID/request". In the response I get a user_object corresponding to userB With relationship == 'pendingThem'.
But userB do not receive any friend request at all.
Any tip? It was working perfectly and just stop working a few days ago.
