WinRT inconsistency(?) with navigation bar behaviour

Hi,

I found an interesting behaviour of the WinRT (UWP) app’s naviagtion bar on
the Lumia 550 (other phones may be similar):

  1. If I start the app from the app list, the navigation bar becomes
    transparent and auto-hides after a while. It can be “wiped in” again (being
    still transparent), and it auto-hides again (either touching the screen
    somehwere else or a timeout, I don’t remember exactly) - just as intended.

  2. If I start the app from inside the store app, the navigation bar stays on
    screen, and is not transparent. You can “wipe” it out though to get the
    desired fullscreen. Not a big issue, but interesting behaviour nevertheless.

A simple google search did not reveal any clear answer as to whether the
navigation bar behaviour can be influenced programmatically or not. Does
anybody know what’s up with this?

Regards,

Daniel
