The link doesn't work on thank you page

I have
added a facebook link to the thank you page that is shown after submission but
clicking on the link does not go to the page, it appears to try and go to the
url but then stops and stays on the same page?
Thanks,
Lee

I've cloned and tested your form and I am not able to reproduce the same issue that you’re having.When I submit the cloned form, it successfully redirects to Facebook without any issues.

We would appreciate it if you could also test it on your side and let us know the result.
