What is browser cache? 

Your browser's cache is a temporary folder where recently visited web pages are stored. As you navigate to different web pages, your browser will try to load these cached pages to save time and allow web pages to load faster rather than downloading them again. 

Occasionally, some of this saved information can become outdated and cause web pages to not display properly, or at all, or for certain elements on the page to not work. Clearing the cache replaces the outdated information by reloading pages directly from the web server, thus providing you a fresh copy of the web page and improves overall performance.

As a best practice, restart your device after clearing your cache.
