We have added a new feature to see which online users have opened the same back office form at the same time. Now you can be very sure that you are the only user in a particular object form while editing it for example. This feature only applies to object forms in the back office.
Online users who have opened an object form at the same time are shown in the form header at the top right (as dots). This feature is disabled by default and could be enabled in the application settings (in my Betty Blocks environment).
