I have two dev orgs set up and have been experimenting with Lightning Connect in them. Recently in one of my dev orgs I cannot delete the external object associated with the external data source. I can still do so in the other. When I try to delete the external object I get the message "Insufficient Privileges - You do not have the level of access necessary to perform the operation you requested. Please contact the owner of the record or your administrator if access is necessary." It's a dev org; I am the administrator. Any suggestions on who to contact or troubleshoot would be appreciated.
