Is my form uploaded?

No. Forms often hold personal details, so it's filled inside this tab, and the page's security policy blocks it from sending data anywhere.

It says my PDF has no fields. Why?

Some forms are only printed lines, with no real fields inside the file. Use View and Edit PDF for those: it places text, boxes and your signature anywhere on the page.

What does locking the answers do?

It flattens the form: your answers become part of the page and can no longer be changed in a PDF reader.
