Shadows on mobile

I found the solution.
The following options were disabled in project settings (my bad):

Support Combined Staic and CMS Shadowing
Support pre-baked distance field shadows.

Enabling them, adds the shadows again.

Hi all,

Whenever we create a mobile project (vulkan), using a basic FPS/VR whatever template. There are hardly any shadows that appear on the floors or walls. Even when increasing the lightmap resolution of the architecture to 512, shadows do not really appear (apart from a few blurry spots in some occasions).

Is there a way to improve shadow quality on mobile?

Below are expamples of what I get with a cube (static) and a basic light source (stationairy).

with Vulkan preview render:

This is when using the default SM5:
