Are layouts rules reflected in the mobile app ?

Are layouts rules reflected in the mobile app ?

Hi,

I programmed some layout rules for my potential module, some showing sections and others setting mandatory fields based on the stage of the potential.

It seems to work fine on the desktop version. 
However, I don't feel them being reflected in the mobile version (I'm using the iOS one) and as most of my team are using the mobile app 95% of the time, this function is kind of useless if it's not working on the mobile app.

Is it normal ?

Thank you,
