Language toggle working on desktop but not mobile

Hi there! Having some issues with this code which works perfectly fine on desktop but not mobile and I can't figure out why.

The website is French and English, the language button is meant to bring the user back to the same page they are on but in the other language. This code works fine on desktop but on mobile... it brings the user back to the language button set URL slug. Help!

<style>
  /* hide items on desktop */
nav.header-nav-list>.header-nav-item:nth-child(odd) {
    display: none;
}
/* hide items on mobile */
[data-folder="root"]>div:first-child>div:first-child>div:nth-child(odd) {
    display: none !important;
}
</style>
<script>
  window.addEventListener('load', function () {
  document.querySelectorAll(".header-nav-item--external a").forEach(function(t) {t.href = "/fr/our-services"});
});
</script>

Because your script code target Desktop Header Nav items only.

What is your site url? We can check Mobile nav easier

Try changing code to this

<style>
  /* hide items on desktop */
nav.header-nav-list>.header-nav-item:nth-child(odd) {
    display: none;
}
/* hide items on mobile */
[data-folder="root"]>div:first-child>div:first-child>div:nth-child(odd) {
    display: none !important;
}
</style>
<script>
  window.addEventListener('load', function () {
  document.querySelectorAll('div[class*="-nav-item"] a').forEach(function(t) {t.href = "/fr/our-services"});
});
</script>
