Form not submitting - 'Please Wait' on screen

I have tried testing this form and it is not going through. The same happened on this form 2 minutes ago too:

Hi @pihms,

I just made a test submission on your form but was not able to replicate the issue. The form submitted successfully and I received an email as well.

In case you received the same error, could you please provide us a screenshot of the browser's console logs so we could check? Please see this guide on How-to-Post-Screenshots-to-Our-Support-Forum.
