Page-content padding-top android

Hi,
I’m trying to maintain my app on both iOS and Material themes following the tutorial at https://framework7.io/tutorials/maintain-both-ios-and-material-themes-in-single-app.html
I’m using fixed navbar in both case.
I found a strange behaviour.
On iOS all is work fine as the theme for iOS put into page-content a padding-top of 44px which means that if I put an image just on top, it touches the navbar.
The material team instead put into page-content a padding-top of 104px which means 44px of free space between navbar and beginning of page-content. To make it look correct I should set a padding-top of 60px…
Is this correct or am I doing anything wrong?

Do you use v1 or v2?

                       I'm currently using V1
