How do you remove a Map from 6.1r1. How do you remove the map from the device group on the dashboard?
Hmmm. What widgets did you have beforehand that got migrated to this version of HiveManager? If you go edit that tab of the dashboard you'll see the list of widgets with checkboxes on the left side of the screen. Are any of these specific to a map? Could you try unchecking them and then go back and attempt to remove the map?
