Include all chat history after inviting someone to chat
I Invited someone to an existing private chat with "Don't include chat history" when I intended to share the entire chat. Only option I see at the moment is to kindly ask the person to leave the chat (can't kick them or change the historical chat history setting after the fact). Then, readd them with the intended setting.
I've had the same issue. The workaround of having them leave and adding them back with the correct item marked did not work for me either.

Well that didn't work, when the user rejoined the private chat it just reopened their existing chat without history. :(
