Mobile font not displaying correctly

I used a custom font, and when I look at my website from my iPhone, one of the fonts is not displaying correctly (but it displays fine from a desktop view of the mobile site). I tried troubleshooting based on other pages, and I was able to correct other parts of the pages, but I cannot seem to fix this one spot (my h4 font on the homepage where it says "Depicting heartfelt moments with compassion, ethics, and affordability. Your trusted lens artist ready to capture your story." 

code below:

@font-face {

    font-family: 'NotoSans-Regular';

       src: url('https://static1.squarespace.com/static/646c01b637212461404fc693/t/646c04fe01a02d301c9dd94f/1684800766307/NotoSans-Regular.ttf');

  }

p {font-family: 'NotoSans-Regular';}

@font-face {

    font-family: 'GothicA1-Regular';

       src: url('https://static1.squarespace.com/static/646c01b637212461404fc693/t/646c064cd54c30256427d8b0/1684801101677/GothicA1-Regular.ttf');

  }

h1 {font-family: 'GothicA1-Regular';}

@font-face {

    font-family: 'GothicA1-Bold';

       src: url('https://static1.squarespace.com/static/646c01b637212461404fc693/t/646c04f3d57d9665a19bc27e/1684800756332/GothicA1-Bold.ttf');

  }

h4{font-family: 'GothicA1-Bold';}

@font-face {

    font-family: 'GothicA1-Bold';

       src: url('https://static1.squarespace.com/static/646c01b637212461404fc693/t/646c04f3d57d9665a19bc27e/1684800756332/GothicA1-Bold.ttf');

  }

h3{font-family: 'GothicA1-Bold';}

@font-face {

    font-family: 'GothicA1-Medium';

       src: url('https://static1.squarespace.com/static/646c01b637212461404fc693/t/646c0aedf5829b41977f9623/1684802286227/GothicA1-Medium.ttf');
  
}

h2{font-family: 'GothicA1-Medium';}
