[Web Service] after updating the web map, I couldn't see the update in the Google Drive File.

Background

• I create map on the Xmind Web Service.
• I link the map to my Google Drive account.

Situation

• I couldn't have the preview once I click the Google Drive File.
• I did several updates on the Xmind Web Service File, however, I couldn't see those updates on Google Drive File.

Thank you.
