I do not see move bar in my vivosmart 4, it gives move alerts but not the graph. The feature is in specs. Is it a bug in software or not provided anymore?
Do you mean the movement tracking? It should be on your graph in the "all-day heart rate" page. If you dont see it you can activate it by click on the word "movement" located underneath the graph.
I am not sure what feature you are talking about. Maybe you have a VivoActive and not VivoSmart. But you can add widgets for Calories, intensity minutes, distance, steps etc, in device settings in garmin connect.
