Unable to revert back to default thank you message.

I just changed the Thank You page to a website URL on the builder, but now I cannot change it back. Please help!

Do you mean to say that you want to again display the default thank you message?

You need to just click on the "USE DEFAULT PAGE" button and that will restore the default thank you message. Please check the screenshot below:

Do get back to us if you have any questions.

Thank you!
