Issue
When launching the game, it enters immersive mode. However, after tapping a text field, the system bar appears and doesn't go away, even after dismissing the keyboard. This partially obscures the main content area.
Steps
Launch the game
Tap New world
Tap name field
keyboard appears
system bar appears
Dismiss the keyboard
Expected
Keyboard disappears
System bar disappears
Actual
Keyboard disappears
System bar persists
Possible Solution
It seems that the system bar appears to allow for a menu icon. This is a legacy feature.
Replace the legacy menu button with an on-screen one
