Success message now showing after submitting form


I’m not sure how to debug the issue with my form. The form appears after 5 seconds. I input my name and email and then after submitting the form, there is no success message and it redirects to a new section on the page (which is correct).

There is a success message that the user should see after submitting the form but I’m not sure how to solve this issue.

Here is the link to my project

Here is the link to the designer

Thank you in advance!
