How Do Group Chats Work With RCS and Non-RCS Members? Hypothetical here since I don't have RCS yet, but assuming I and a few of my Android friends get it in the near future, how will this impact my group texts? Will the *entire* group chat (as in, all of its members) have to have RCS UP to reap the benefits in that chat? How bout if it's a mixed-OS group chat?

Thanks!
