i’ve a problem with my app.
Today i’ve upgrade my android studio to the last version.
I’ve runned my app on my phone, but in the activity_main.xml the include layout (that contains a new ActionBar) doesn’t show the new actionBar, but show the image behind my smartphone.

Kotlin Android app has a BottomNavigationView on the initial fragment. When the app is run the first icon of 5 in the view shows but the remaining icons/labels only show when that (blank) part of the navigation bar is clicked. app:labelVisibilityMode=”labeled” is set as indicated.
