I followed the instructions in the following link:
Upon completion of a test survey, the email is sent to the supervisor but the edit link takes the supervisor to the survey complete page.
How do I get the supervisor to the correct page?
Hi there! I just put in a testing response in your survey, and it worked fine for me. When you’re testing this, are you just taking the survey with the Default Link, or are you going through the Test tab or something like that? I don’t think that this will work properly through the Test tab. If you’re taking it through the Default Link and it’s still not working, let me know, and I’ll see what else we can do!
