why can't i rename a group chat?
I looked up how to rename a group chat, but when I actually tried doing it on my phone it didn't work. Why?
iPhone 6, iOS 8.4.1
As I recall, you an only rename a group chat if all the members of the chat have iPhones. If there is anyone in the group who has a different kind of phone (e.g. Android), you can't rename the chat.
