The Nokia 6.1 Plus updated to Android Pie 9.0 today (Oct 31). But still the *hide notch* option has not been included, while Nokia had said they will fix the issue with the update. Moreover the Nokia Camera app still does not have Google Lens integration, even the Google Lens application is incompatible with the device till now.
The new gesture button icon does not show when it is used for sliding from one app to another. And the gesture panel also turns and remains white at times when theme preference is changed to Light or Automatic(based on wallpaper).
