To leave a conversation, tap Details, then tap Leave this Conversation. You can only leave group iMessages that have at least three other people.
Appreciate your response.
I think I had used that option before and during a text string with family one of my brothers was complaining so I told him he could opt out. He asked how and I looked on my phone for how to do it but it wasn't there. I did go to details and I just went there again but the "Leave this Conversation" option is not available now. Frustrated.
how do i remove myself from a text string?
