On my Samsung Galaxy S8 Ultra, I noticed that having Display Settings -> "Fullscreen mode" actually does the opposite of hiding the notification bar in all screens. It initially works, but if the tablet sleeps for a while and I wake it up, the status bar will suddenly appear when viewing sheets, and it does so in translucent mode (it overwrites visible sheet elements as well as the mobilesheets clock). This might be happening if I have "hide navigation bar" and "dim navigation bar" also set to on (I haven't tested each combo extensively).

For now, "Hide navigation bar" does what I need - it shows the navbar in the library, but hides it reliably when viewing sheets.
