Our team has identified the issue as being related to new default Referrer Policy behavior in Google Chrome 85. This issue can be rectified by defining a compatible Referrer Policy for pages with FormAssembly forms embedded on them; such as
no-referrer-when-downgrade which was the previous default policy for pages where no Referrer Policy was defined.
Inserting the following <meta> tag anywhere on the page, preceding the form, will allow forms to function properly:
<meta name="referrer" content="no-referrer-when-downgrade">It is recommended that meta tags be added to <head>. It is possible to add the <meta> tag to all forms using Advanced Branding to include it in the form <head>. The <meta> tag can also be added to the Custom Code section of a form.
Note: This will override any Referrer Policy you may have set for your pages. If you have set a specific policy other than "no-referrer-when-downgrade", please review the following document for any potential impact this may have: MDN web docs: Referrer Policy
