Hi, I am using an ipad2, IOS 7.1.2 My facebook chat sidebar that used to be on the right hand side of the screen as I face it has disappeared. It may have been around the time of a facebook update, I am not sure. It showed a list of my chat friends and indicated who was online and I used it all the time. It has suddenly been replaced with a list of trending topics (possibly on messenger) and adverts. There is no little gear wheel to click on to enable/disable the chat sidebar, it has simply vanished! Can anyone help? Thanks in advance.
