What is browser cache?
In order to speed up web browsing, web browsers are designed to download web pages and store them locally on your computer's hard drive in an area called "cache". Browser cache (also know as Internet cache) contains records of every item you have viewed or downloaded while Internet surfing. So when you visit the same page for a second time, the browser speeds up display time by loading the page locally from cache instead of downloading everything again.
Although storing Internet cache makes web browser faster as it usually takes your computer less time to display a web page when it can open page's elements or even the entire page from your local Temporary Internet Files folder, you sometimes want to overrule the Internet cache.
If we update a small bug, issue or change something in your account, you may need to override the stored cache and pull down the new data from our servers
So if our Support team ask you to do a "Hard Refresh" your browser to fix something. Depending on your operating system all you need to do is the following key combination:
Windows: Ctrl + F5
Mac/Apple: Apple + Shift + R or command + Shift + R
