I want to delete/remove/hide/archive completed sprints from the big picture tool main dashboard but I am not able to figure out a way to do that. If I try to delete closed sprints, it gives an error, "Cannot delete box PI-1 when Automatic sprint-based timeboxes option has been enabled. You can edit sprints in Jira or change timeboxes settings in the box configuration." I can't find the settings to disable it.
And what about archiving, it says that we cannot archive the sub-scope manually. whats the other way to do that?
