IOS keeps loading font-face font

Question

css

Such a problem:
I specify the style

@font-face {
    font-family: 'Segoe UI';
  
    src: local("Segoe UI"), url('/fonts/segoeui.ttf');
    font-weight: normal;
    font-style: normal;
}

Everything works great everywhere. But on Windows, the font is not reloaded (taken from local), but on the iPad it constantly loads. and at first the text is not visible at all, it appears gradually.
How to make IOS remember the font?
