We have imported dashboards from one EH device to another. I have system privileges, yet it does not give me the option to edit the dashboard.
Regardless of system privileges, dashboards can only be edited by the user that created the dashboard, or by users who the dashboard creator has explicitly given edit permissions to on a dashboard. Feel free to open a support case at https://customer.extrahop.com/cases/create/ or by emailing firstname.lastname@example.org if you would like additional assistance with modifying these dashboards' permissions.
