What is JotForm?
JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
At JotForm, we want to make sure that you’re getting the online form builder help that you need. Our friendly customer support team is available 24/7.
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.
That should not happen. Upgrading/downgrading your account have not effect on your form or submission data.
Unfortunately, we don't maintain the versions of your form so I am afraid that you may have to redo the changes to your form.
Please let us know if you encounter this issue again and we will investigate on this.
