How do I add thank you for submitting

Hello,

i added my puppy form but when I did a sample I found there is just a empty screen Vater submitting. Not thank you or thank you for your information or thank you for submitting. How can I add that? It’s more friendly that way

 Thank you

Apologies for the inconveniences caused. 

I've cleared your forms cache and tested your form, I can see the thank you message displays normally: 

May you please test again and see if the problem persists? 

We will wait for your response.
