Did ios 9.1 changed the behaviour of how wifi calling is handled? Before on 9.0.2 the cell signal had to be weak for wifi calling to kick in, now since upgrading to 9.1 it always connect through wifi calling first and then cellular if the wifi signal is too weak or get disconnected...Anyone can confirm that? Im using a iPhone 6s on ios 9.1 and Rogers is my carrier in Canada...
