CORS policy is being blocked for a user

Hi Liz, thanks for the response. The url is embedded at https://app.vyra.ie/

Hi Liz, we have several users of the platform and up until now there has never been an issue with the embedded typeform. This issue is only occurring with one of our users. For this reason, I think that it might be a security measure in place from this companies IT. However, they can still access the typeform from the url.

This is how we embed them:
 

function updateTypeformCards(auto_popup = false) {
  const typeformLinks = document.querySelectorAll('#typeformLink');
  typeformLinks.forEach((elem) => {
    const formID = elem.getAttribute("data-typeform-id");
    const emailStr = elem.getAttribute("data-email");
    const modulePk = elem.getAttribute("data-module-id");
    const firstName = elem.getAttribute("data-first-name");
    const orgName = elem.getAttribute("data-organisation-name");
    const isNext = elem.getAttribute("data-is-next");
    const options = {
      hidden: { email: emailStr, first_name: firstName, organisation_name: orgName },
      onSubmit: (event) => {
        if (formID === "GiV6Ejvn"){
          window.location.href = `/?ready`
        } else {
          fetchTypeform(event.response_id, modulePk)
        }
      },
      autoClose: 3,
    }

    const { open, close, toggle, refresh } = window.tf.createPopup(formID, options)
    elem.onclick = toggle
    var isTrueActive = isNext != null && isNext.replaceAll(' ', '') === 'true';
    if (((window.location.href.indexOf("open")) > -1 || auto_popup) && isTrueActive === true) {
      setTimeout(function () {
        elem.click();
      }, 1000);
    }
  });
}

Hello,. I dont know, this is a weird error message given it happens for single user only. Just a guess - could be related to their browser. What browser are they using? Can they try opening the popup without any browser extensions?
