We have an email form on a webflow page that collects name (non-obligatory) and email. I tried to move our form from a Webflow GET form to a Mailchimp POST form (posting to a list we have on mailchimp), following the instructions in the docs for how to push to Mailchimp, but using a webflow form.
When we published the form to our customsubdomain.webflow.io, it worked fine and showed an inline success message in the page. However, when we published the exact same setup to our custom domain (lingumi.com), the form submit button redirects to a Mailchimp signup page to enter the email address (again).
Is there some kind of bug with custom domains which means the form redirects to the mailchimp hosted form by mistake? We’ve put it back to a Webflow for for now as we don’t want the redirect to happen.
The live form (currently using Webflow GET without any mailchimp tie-up) is at https://lingumi.com/gewinnspiel
