group messaging
After installing ios11.1.1 my iphone SE is no longer able to do group messages. The icon to choose group messaging is no longer showing as an option. When I try to send a group message it is received as an individual message and any return messages to be are also individual messages, not as a group. iMessage and send as SMS are clicked yes. The group message feature worked fine before the ios update. Help!!
iPhone SE, iOS 11.1
