Custom Font Not Showing Up Anymore

Can anyone tell me why the custom font isn't showing up on mobile and now when I go into editing, but it was before?

this is the CSS I used

/ PARAGRAPH 3 CUSTOM FONT

@font-face {
font-family: 'ShadowsIntoLight';
src: url(https://static1.squarespace.com/static/6475062e3a03f32ab1c58c36/t/647506913a03f32ab1c59846/1684265256510/ShadowsIntoLight-Regular.ttf);

}

.sqsrte-small {
font-family: 'ShadowsIntoLight';}
