Chat button

Hi there; It seems like the chat/message function is not working very well. I can't scroll to the bottom of my chats on desktop or android (not using the app) I can get to the 15th chat; and then the actual blog page just continuously scrolls down behind the message box; rather than scrolling down to the older messages / conversations I've had. Hopefully you can understand what I mean. Would be nice to see all my old conversations and not just the new ones! Marcus
