I believe we started experiencing this after we were on Utah instance. We updated plugins before we noticed behavior and do not know if it is related to a plugin or the platform update. If we have an active session, the system behaves as normal. But if the session has not been established yet or if the session has timed out, we cannot load pages when the URL is directly a specific page. All users experience the same behavior. So if I am working on any specific page and I timeout, a refresh will yield a blank page. I can remove all the characters in the url after xxx.com/ and the page will load and drop me to my home page. Then I can navigate as normal. If session is not pre-established, all links to specific pages will fail in same way also. We are using okta, and I can see brief redirects on screen before the blank screen displays. Okta login seems to be successful before the page does not load. Different browsers have same behavior. Deleting cache and browser cache and cookies have no effect. We updated to Vancouver and issue persists.
