Question

I'm using Theme.MaterialComponents.DayNight.NoActionBar for my activity. My goal is to create an activity with no title bar and make the notification bar background as same as app background colour. Everything works fine under normal condition. But when I enable dark theme from the device settings, the title bar suddenly appears. How can I get rid of title bar for both dark light theme?
