Buttons and custom font not responding

I'm having an issue uploading custom fonts for headings and buttons. Paragraph text works fine. For headings, I can use the Squarespace options but it will not respond to the uploaded fonts, even with !important. For buttons, they will not change from Poppins. I've tried several from Squarespace and uploaded a couple custom fonts but it remains Poppins. I've tried clearing cache and viewing from other browsers too but no luck. Help? Thank you!

Can you share your website URL and all of the CSS code you are using to add the custom font?

I tried with and without !important for the headings:

@font-face {
    font-family: Proxima Soft Semibold;
    src: url(https://static1.squarespace.com/static/651dfa29680f6f6fc62f861f/t/6536e9616ef29718568a4e88/1698097505621/ProximaSoft-Semibold.woff);
      
h1, h2, h3 {
font-family: 'Proxima Soft Semibold';
}

@font-face {
    font-family: 'Apercu Pro Regular';
      src: url(https://static1.squarespace.com/static/651dfa29680f6f6fc62f861f/t/654abafc1c857e0377793511/1699396348945/ApercuPro.ttf); 
}

h4 {
font-family: 'Apercu Pro Regular' !important;
}
}

And then I found a couple different options to target the buttons but none of them worked so I deleted it.

It looks like she (the client) is testing out different Squarespace fonts which is overriding the paragraph font now too. It was working previously.

@font-face {
    font-family: Apercu Pro Light;
      src: url(https://static1.squarespace.com/static/651dfa29680f6f6fc62f861f/t/6536ec9c99098c555675431f/1698098332300/Apercu-Pro-Light.ttf);
} 

p {
font-family: 'Apercu Pro Light';
}

Hi @Scandi we can check easier if you share a link to your website.

Can you try changing this code

to this new code. I've added quotes around your declared name, and added closing curly bracket.

@font-face {
    font-family: 'Proxima Soft Semibold';
    src: url(https://static1.squarespace.com/static/651dfa29680f6f6fc62f861f/t/6536e9616ef29718568a4e88/1698097505621/ProximaSoft-Semibold.woff);
}

Let me know how it goes.
