.. unfortunately, this is an ongoing and 'known' issue. It occurs on ALL browsers and whether or not the cache has been cleared, browser has been closed and reopened, or computer has been rebooted.
It's a backend web server issue and most likely is caused by heavy traffic. This does not occur on other sites like HR Block or TaxAct in my experience.
Intuit would do well to stress test and audit their servers and web performance response time.
