Thanks for letting us know about your experience. There some things about the page interaction that we can control directly, and some that we need to work with our IT colleagues to improve. When you visit the site while logged into your account, there's a step that verifies your session/authentication and that might trigger the refresh you're seeing. For most visitors this happens fast -- but 5 seconds is a long delay. I don't consider that to be acceptable. To test quickly if this is a factor, open an incognito/private window in your browser (so you're not signed in, no cookies) and visit the same page where you see a delay.
Offline, I might ask you (or anyone experience a similar delay) to provide a console log so we can see exactly what step in the process is causing the delay you see. In Chrome, you can open Developer Tools (F12 key toggles), go to the Network panel, and refresh the page. You'll see the myriad of resources that load as part of the page along with timings. You might be able to which resource is causing the delay you're seeing, or you can send the complete log to me and I'll dissect.
