Why do I see the challenge page when I submit a contact form on Shopify
The challenge page exists to reduce the spam on the contact forms. It will redirect the user to a captcha (challenge) page should a bot/human test be needed. This is a new way of Shopify helps to prevent spam signups to the various forms on your website, including the email newsletter signup form, the contact form and “back in stock” notification forms.
These pages are typically only shown if the same user attempts to submit a form more than once in a 24 hour period, though it may be triggered in other cases as well.
At this time there is no way to modify this page’s design. There is also no setting in Shopify to turn this confirmation page off, but you can inspect the elements on that page and try and override their CSS if you want to edit the challenge page.
