No "delay" button for agent with OCS 2.3 Server

Hello,

We upgrade ocs server (linux) to 2.3 and agent to 2.3 Windows.

Since, when i configure a deployment package with "Delay" option for user, the button no more appear when notification pop on screen.

PS : make a test with windows agent 2.1.1.3 and 2.3 server : DELAY button not appear.

Upgrade to 2.3 broke this option.

Any solution?

regards.
