First Load bottom toolbar cut off with whitespace

The first load of my app has the bottom toolbar “cut off” by some whitespace. When I change the orientation from portrait to landscape everything seems to recalculate and is in the right place.

Is there something I’m missing for when the app loads the first time for everything to fit within the safe areas properly?

I figured out that the default Framework7 body height style needed to be changed from 100% to 100vh to load properly on iOS devices the first load.
