Form submission and Pardot form handler issue - Windows 10

Hi

I’ve setup a form to be handled by a Pardot form handler once submitted and then redirect back to the same page URL but with some added parameters in order to show different page content. It’s working for all the tests I’ve done apart from Windows 10 with Chrome 103 where, for one tester, the form is submitting but displaying a thank you message instead. The form confirmation is set to be a redirect so this thank you message should not be being displayed

Has anyone else experienced this kind of issue?
