I have a variety of TEXT chats going on in the Google Message app but only one seems to take the form of an RCS chat. I don't know if I care that much but am curious why just this one person and I have created this RCS chain. Is there someway to return this to a normal chat or just start a new chat thread? Should I want all my chats to be "protected" and be in the RCS format? And I guess what would have triggered this behavior so I can either initiate it if I want or NOT initiate it?
