The "start"button translation is not available

Hello guys,

I have created a form directly in Portuguese, and have translated all the warning messages as per your tutorial. However, the "Start" button message is not available in the form settings / form warnings tab neither I could find it anywhere. I need to change "start" to another language. Can you help me please?

To change the language of the Start button, just click on Edit Welcome Page.

Then once you click on START text, you will be able to edit the text. Just remove the Start text and write your own text.

Here is the result:
