Why am I getting "Timeout" alert every now and then?

If you open one of The Scheduler pages in JIRA (like "Scheduled Issues" tab panel) and leave it open for 1 hour, you'll notice a warning alert asking you to refresh the page. This is because The Scheduler uses so-called JWT tokens to authenticate the communication between its server and your browser, and this token has a validity limit. Unfortunately, as of now, we cannot automatically extend its lifespan, which means that you will need to refresh the page after 1 hour of inactivity. We're hoping that Atlassian will soon provide us with a way of "refreshing" the token under-the-hood, so that we could do it in the background and hence do not need you to refresh the page. As soon as it's possible, we'll get rid of that alert!
