Hi, When we have user teaching, we encourage our use the templates we have prepared. We share them out of our private KNIME HUB instance. Those templates will often have Components which we manage, plus Extensions. For example, in this case a Component that helps create a secret for the user. But when the user “Drag-and-Drop” from the KNIME HUB, the interface is being locked up. The “Checking Link Updates” is waiting for “Extension install” and vise-versa. Currently, we have to open Task Manager, kill KNIME. Open KNIME. Install Extensions manually and then drag-drop the template in. [image]
