When you open the app and tap somewhere on the map, the are two buttons: navigate and marking. Once the phone is switched off, or the app is put in the background, the navigation button disappears and the marking button gets larger. The app must be closed and reopened to get back the navigation button.
when you freshly open the app and tap on the map, you see both buttons, navigation and marking (left picture). Switch of the phone and open it, or put the app in the background and go back to it. then you see only one large marking button (right picture).
Confirm, for me too
