Team City web interface caching

I'm seeing this a lot lately, and not sure what to do, so I'm hoping y'all can help.

Running TC 9.1.5 on a local server, as a distributed team with automated CI builds. What's happening is that a developer makes a checkin, and the code starts building, and he sees that change in the UI. On the other hand, I refresh my UI and the most recent activity is over an hour ago. He checks his version of the UI, and sees the build building, I refresh, and still do not see any updates. 

Sometimes navigating away and back will work; sometimes it won't. Sometimes after a while, it'll just start updating again. Sometimes we'll end the day and it won't have updated.

So what I guess I'm asking is "when I see this behavior, how can I unstick it?" It'd be really handy to be able to trust the UI, but even when I can't, is there a way to force a refresh from the client side? Is there something I can recycle on the server side?

Thanks
