I have the same problem ... I hope solve this problem soon.
Maybe it was delayed, did you check again now if the submissions went through?
If not, please re-integrate your form again to Google Spreadsheet but before doing that, please clear your browser's cache first. See if this makes any difference.
If the issue persists, please update us here so we can assist you further.
