Sometimes it can take a while of spinning before it goes through. But if the entries never show up in your Sheet then one of these things might be the reason:

  1. Wrong access code ( Check debug log )
  2. Wrong Sheet name or tab name
  3. Wrong Column name mapping ( Column names are the contact form mail-tags. It cannot have underscore or any special characters )

Please double-check those items and hopefully getting them right will fix the issue.
