I have a group message with 8 people in it. We all have iPhones and the new iOS8 software. Once we got the new software someone renamed the group. Ever since the update, randomly it will happen that when someone responds in the group... instead of the response showing up in the group we already have... it creates a new group with all the same people. This does not happen every time it is random. This is very frustrating, someone please help!
