Unable to change group text name or add person to some group texts in iOS 8
I really like the ability to change group text names as it helps me separate work group texts from personal especially when I have coworkers that have separate business phones. I'm unable to change the name of some group texts as the option is not there when I go into details. I'm also unable to add contact to the same group texts that I'm unable to change the name on. Is this a glitch or am I missing something?
iPhone 6, iOS 8
