Features

Bug fixes and improvements

• The app is now considered as the one in active navigation only when an active route is set to MapboxNavigation. Previously it was always considered active. [#7366](https://github.com/mapbox/mapbox-navigation-android/pull/7366)
• When Android Auto host tells the app to stop active navigation because another app starts navigating, now SDK will enter FreeDrive mode instead of stopping trip session completely. [#7366](https://github.com/mapbox/mapbox-navigation-android/pull/7366)
