When a Web-based application, such as a Web site, is updated, it may be necessary to clear your browser's cache. This is because your browser caches certain data, such as images and styles, to make the website load faster. After an update, this can cause the browser to still load the old data and not the new, updated data from the website.

Clearing your browser's cache removes the old information and allows the browser to load the new version of the website. It is similar to buying an updated version of a book after the content has been changed. Clearing the cache helps fix problems such as display errors or missing features on the website.

I hope this explanation has helped you understand why clearing your browser's cache after a Web-based application update is important. If you have any questions, feel free to let me know.
