Endpoint Encryption

Hi,
When we are formatting computer, installing Symantec Endpoint Encryption, adding 6 domain users and 1 local (pgpadmin), and encrypt HDD/SSD, all users can use the computer normally without any problem for next 2-4 month. After they begin have problem with sign-on. In shift time, when one user change another they restart computer, and second user wanna to sign-on in his account - he cannot sign-on by his account, system opens with previous account, not new. What can do we with this problem? Can you give to us any suggestion?
Best Regards,
Kamran Musavi.

What version of the product is in use?  There was an issue in some older versions with Windows 10 when fast startup is enabled.  This should not happen on the latest version.

The workaround if you don't have access to the newest version would be to disable hibernation and fast startup on the systems.
