We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
If I understand correctly, you do not want the Thank You page to show up after the user submits the form? If that is so, then you can simply redirect the form to your own custom page after submission to prevent the user from seeing the Thank You page. Here's a guide on Redirecting Users to a Different Page. Please let us know if you need further assistance.
