Remove shadow from ion-nav-view

I’m really getting crazy on this.
How do I get rid of the horizontal shadow that appears during the slide transitions of ion-naw-view?
The target is IOS but this shadow shows both on device and ionic serve.
You can see the actual shadow here under the three buttons.
The header is custom. The main component is ion-nav-view.
The shadow shows up only during the transition. Push transition in this case.

Any help would be really appreciated
