Mailchimp integration works only sometimes

Hello guys,

The team and I have tried troubleshooting the issue regarding the form sometimes not working; the ‘oops’ error message pops up. We believe there is something with the email field, but everything works perfect from time to time. And the fields are 100% correct linked to Mailchimp (checked countless of times). The reason we expect the issue is on Webflow’s end is that the actual form works 100% if filled out inside of Mailchimp
