Session Timeouts shorter than policy

[Christy Johnston]

We currently have a policy of 2 hours for our Atlassian users. However, it appears to time out sooner than the allotted amount of time. A running theory I have is that the session is not updating when a user opens a new browser window and seems to operate off another idle window running in the backlog.

Can someone point me to an explanation or remediation?

Thanks.
