Why don’t I see the body of my form when I look at my submissions?

All I see is the signature and date of submission

If you are referring to the text in your form, they are not shown in your form submissions page by default. To reveal them, you have to check the "Show Headers and Texts" on the submission settings.

Example:

If you have it to appear in the notification as well, you have to manually copy and paste the text there.

Hope this information helps!
