Following a history auto save operation on a watch paired with iOS, a URL is shown in "Memo" area of the calendar, but tapping the URL causes the following message to appear: "Unsupported file type".
With iOS, this error message appears if a file is not supported by Google Drive.
If this happens, tap the more menu icon (...) in the upper right corner of the error screen. Next, tap "Open in" and then "Copy to Google Earth".
