While using Google Hangouts on my Moto X I do not receive groups messages from certain people. However, I do receive messages from that person in a one to one message. I just recently switched from an iPhone 4 in December 2013 and have been having this issue ever since. I have tried to unregister my number from iMessage and Apple and that seemed to work for all but one person. This is driving me crazy. I love my Moto X but may have to switch back to my old iPhone to fix this problem. Please Help.
