I am stuck in the middle of a group text that has gone off on a tangent and is no longer relevant. I heard that one now has the option to leave a conversation, but my iPhone 6 running iOS 8.02 only gives me the option to quiet the conversation but not to leave. I don't have unlimited texts so I really would like not to use my limited texts on meaningless chatter. Is it because all of the people in this conversation don't have iPhones? I've looked at the options under details ten times and can't find the "delete me" option. Am I completely missing something ?
