Thanks!
But the problem seems to happen after the sheet is moved to Team Drive. We tried to rename the sheet and tab and do it again, but it did not work for any forms.
After submission of the form, it is redirected to a blank page with a single line as shown below
Fatal error: Call to a member function getWorksheets() on null in /home/grtalenthk/www/www/wp-content/plugins/cf7-google-sheets-connector/lib/google-sheets.php on line 75
We are still able to get the email confirmation but the info does not go to Google Sheet.
