Blank page when loading app - IOS devices

App: https://share.streamlit.io/magnesyljuasen/bergvarmekalkulatoren_v2/main/main.py

Github: GitHub - magnesyljuasen/bergvarmekalkulatoren_v2

The app seems to work fine, but when opening it on an IOS device it does not load the app but a blank page.

Same issue.
My streamlit version:1.9.0. Working well on windows computer, but blank on iOS device (both Chrome & Safari)

After testing, ios mobile phones including X, 6S, 6S plus cannot display streamlit.
It is speculated that iOS mobile listed before 2018 cannot display streamlit.
