I created a new custom property for nodes, and I can update the values for that custom property. But it does not show up on the Node Details page.
You want to check the box on the custom property page for usage, specifically 'object Details Views' If that doesn't do it, make sure information is set for that device for that property as well.
Check and Edit the Property on that Custom Property to make sure that the Include Object Details Views is checked for that property to appear on the node details page. (All Settings - Manage Custom Properties)
Also make sure the Custom Properties Widget is on the Node Details page.
We have already included Object Details Views while creating the custom property.
Also, we are not seeing the assigned values for this newly created property in manage nodes page.
