Cover images on mobile are not shown in full width.
On desktop:
Showing the full width. If needed make it smaller in height.
Same on Android. It seems the scaling and positioning as set on Desktop is not taken into account, as well as a different default positioning compared to Desktop if the default position and scaling has not been changed on Desktop.
Current implementation does not take into account image proportions we just scales cover image to fit in fixed height.
