We send emails with prefilled linked to forms to thousands of users. Some macOS users running Safari cannot open the forms. They click on the link in their email client, and Safari opens a window showing nothing but a white background.
Since we lack the staff to troubleshoot individual technical issues, we tell them to try Chrome or Firefox. But some users don't have other browsers installed and lack the skills to install a new one. The call I took last week was from a user who clearly wouldn't have been able to install extensions that could have interfered, leaving us puzzled.
Is there anything else we can do to make our form more compatible with macOS and Safari? We are prefilling several fields, which remain hidden, and display a thank you page after submission. The form is opened by clicking a link in an email; it is not embedded into a Web site.
