Some submissions do not appear on integrated Google Sheet

Some form submissions do not get added to the integrated Google Sheet. If I remove the integration and recreate it, all of the entries do populate. 

We had issue with our Google spreadsheet integration earlier. But it had been seen reverted to and fixed by the back end team.

Please try first doing a re-integration process and see if it resolve the issue.

Remove the existing Google spreadsheet integration on your form, save the form, and then re-integrate again.

You can check in your google docs account if the spreadsheet is now properly updated with the form submission data afterwards.

Hope this help. Let us know if issue remains.
