It looks like Messages are not grouped so conversations with people don't group long conversations together. Instead each & every message is it's "Own" message now so now its very difficult to look back at data in a message. Scrolling down through data which is how it has been so wonderful, until now.
May you consider reverting messages to the classic old style? Now I have 17 pages of single messages to people each one individual so I guess if it kind of makes me uninterested in the website, then I suppose that is the way it shall be.
