My app is an master-detail map, all seems to be working ok but when I enter to the detail view, I go back to the master view, and then I try to go again to the same detail view. The second time the cell stay in a gray color and the app doesn't enter into the detail view.If you create a new master-detail project and you execute the template with no changes, you get the same bad behaviour.I'have tried with both xcode 11.2.1 and xcode 11.3 with no result.
