• [SaaS] If a user enters an invalid email ID with a domain name that belongs to a configured Tenant, the user will be redirected to Azure
to login. [DDPCE-10214]
• When using Google Drive, canceling an in-progress upload and immediately re-uploading the same document creates 2 stored copies
of the document. To work around this issue, instead of canceling an upload, allow the file to upload completely and then upload the
correct document to overwrite the first document. [DDPCE-10633]
• Added 11/2018 - In rare circumstances, when using Dropbox and attempting to perform multiple file changes, Data Guardian may stop
updating, and appear hung. To work around this issue, if the DDG application enters a hung state, re-start the application.

a default instead of the local folder. [DDPCE-10662]
• When Data Guardian Audit Data is enabled by policy, a hidden watermark used for tracking purposes is not properly updated or added
to a protected document when the file is modified. Audit events involving the protected file's modification or creation are properly
logged as expected, though "beacon" data will not be available for that file. [DDPCE-10667]
• When an external user attempts to access embargoed files that are expired or have future embargo dates, an incorrect message is
displayed stating that the wrong Dell Server was being contacted for access to the file. The correct message displayed should alert
the external user that the embargo date is in the future or has expired. [DDPCE-10669]
