As we previously communicated, the new Google Drive UI is now the default experience for all users. On July 7, the ability to revert to the old UI is being removed. We recommended a browser upgrade for Google Apps users as the new Google Drive UI does not work with older unsupported browsers. Users should upgrade their browsers no later than July 6, 2015. MiWorkspace users should not experience any issues as their web browsers are automatically upgraded. For more information, please see Full launch of the new Google Drive UI.
