We get asked this question a lot. There is ONLY ONE reason you aren't able to see Responses in Google Forms, and are able to see the Response on AutoProctor: the student has not clicked on the Purple Submit button.
As we explain here for Timed Tests, and here for Proctored Tests, the student has to click on 2 Submit buttons to finish the test. The Purple Submit button is inside the Google Form. AutoProctor loads the Google Form within its own site. This means that whatever usually happens with a Google Form happens with the Google Form on AutoProctor too.
You can continue reading below for more details:
AutoProctor loading Google Form within its site is similar to how YouTube videos and tweets from Twitter are loaded on other sites. If you click on a YouTube video on a different site, and there is an error loading the video, you will correctly conclude that the error is with YouTube. Similarly, if you face any issue with a Google Form on AutoProctor, the issue is with Google Form. There is literally nothing we can do, as Google doesn't allow us to access what happens within a Google Form.
