When the user submits the form, the response is recorded in Formfacade and Google Forms. If there are any issues with submitting the form or recording the responses in Google Forms, we show an error message to the user and also send a notification email to the form creator. The submit can fail because there is an issue with the form, internet connectivity issue etc. The notification email will include the error message, draft id, link to the response (abandoned or submitted). The error for response #18 shows "Not able to update this response in Google Forms''. This indicates that the submission was successful and the response was recorded in Formfacade, but not updated in Google Forms. Google Forms might reject the responses if it fails any response validations (incorrect answers, missing answers for required questions or if you have enabled any of the features that require signin such as limit to 1 response, collect email address - verified input, send response receipts. Your form is set up correctly. You might have also noticed that sometimes Google Forms throws a "Something went wrong" error without giving any additional details. Login to Formfacade > click on the form to open it > Edit page will be displayed > click Responses > click on the response #18 to view the details > click on the three dots more icon > click Edit > the response will open in a new tab > click Submit and check if you are getting any error or if the response is recorded in Google Forms.
