I updated OD on my computer and published a new Operations View with a new Web Map populated with a Map Service. I have set the OD program to refresh the dynamic Map Service every 5 seconds. This refresh works in the actual program, but does not work at all when using the Browser version of the OD. So far, I have tried IE 10 and Chrome. Is this a known issue?
However, if you are just trying to get the data to refresh on the map, you can do that. You need to set a refresh interval on the map service layer in the map when authoring the map, and then in Dashboard set the refresh type to use the layer intervals (not to use a single interval).
