Spreadsheets error: 'Error fetching the list of spreadsheets'

After connecting to your Google Drive account, you may see the error message: there was an error fetching the list of spreadsheets. If so, you need to allow Google Drive permission to share data with Geckoboard.

To do this, open the Google Apps control panel and navigate to Apps > Google Apps > Settings for Drive, and make sure "Allow users to install Google Drive apps" in the "Data Access" menu is enabled.
