Thank-You page: Redirect to Page not working

Please answer to info@aktecweb.nl

We would like to apologize for any inconvenience. However, it seems to be working fine on my end. Any particular for you're working on and the link to where you would like to have your form redirected after submission?

Have you tried submitting your form after opening it in a browser?

Can you try it again on your end by making a test submission, please?

We will wait for your response. Thank you.
