Adding different fonts to the same line with Code Blocks...BUG!

Site URL: https://round-flower-wm3z.squarespace.com/

Hello, I wrote the following code block to add different font styles to the same line (below), and the correct font-family appears for me on desktop view but not mobile view. The client is reporting that they do not see the font style on either view. 

<h1 style="text-align: left" >Amaro Freitas<span style="font-size: 10px; font-family: Futura LT; font-weight: 1" > LIVE STREAM</span></h1>
<h1>Dandara</h1>
<h1>Simone Santos</h1>
<h1>Yara Borges</h1>

Please advise!

You mean font: Futura PT?

Add to Code Block

<style>
  div#block-yui_3_17_2_1_1596104592881_202211 h1 span {
    font-family: futura-pt !important;
