Empty space under webview

[janpeterka]

First time creating native app, using mostly Hotwire Native for Rails developers for it.

We created the app, and it's working nicely on older iPhone (without rounded bottom), but on newer ones (and in emulator), we get this weird behaviour:

Screen.Recording.2026-06-10.at.13.57.58.mp4

Bottom navbar is web-based (we are not switching to native as we don't know how to show notifications indication - see #242), using fixed position on bottom of the screen.

Is there maybe some setting for full height/ full screen of the webview?

Thank for any help

Tried opening the webside in Safari in emulator, and realized it might be partly mobile safari bug, or some problem on "Události" page.

So, only the other tested ("Nástěnka" and "Příspěvky") are relevant for the issue reported

I think that it might be connected with this issue:

It seems to me, that the browserbar, that "should be" rendered under the app navbar sort of exists theoretically, but it is not really visible. So the viewport is calculated as if it was there, but it stays hidden.

Is the behavior the same in PWA and in the native app?
So is the problem limited only to some pages, or to all pages?
