The browser doesn't display the page correctly

Your browser saves copies of the pages you visit in the cache to reduce traffic consumption. When you view these pages again, the browser can load their data from the memory. For example, if the browser loads your inbox page from the memory, you'll see an outdated number of new emails.

Try refreshing the page to force it to load data from the internet.

If the problem persists, clear the browser cache and delete all cookies.
