If you have created a vWorkspace application that is published by device name or IP address this will not be visible to users connecting from an iPad
The iPad Connector does not parse the device name or IP address to the connection broker when making a connection .The connection broker is therefore not able to return the application icons for those applications published by device name or IP address, since there is no match.
To avoid this issue do not use publish applications based upon device name or IP address for iPad users. Either publish the applications based on username or OU.
The defect has been submitted to the vWorkspace development team for consideration in a future version of vWorkspace Connector for iPad
