I am trying out Lightning Service console in my sandbox to view my Cases.
After Edit Page -> Activate -> set as org default -> save -> back.
The Case Record Page Layout is still the default layout.
When I click Edit Page again I found that the layout I am viewing is not the layout I saved.
For example, I saved my Layout as Casae_Record_Page. But when I view my case again, the layout is a new Casae_Record_Page1. It seems the Lightning service is not able to recognize my custom layout ( which is set to be org default). That why It's opening a new default layout for me(which is Casae_Record_Page1).
