If you're not seeing acknowledged updates to PMAPS or the page is not loading to display correctly, your browser may be cached. Caching refers to temporarily storing data in a way that can be retrieved more quickly later. Web browsers use caching to improve the performance of frequently accessed pages.  When you visit a web page, certain files for it are downloaded and stored in your browser's local cache. If you return to the page later, those files can be retrieved from the cache instead of re-downloaded from the web server. Most of the time, caching is desirable and provides a better web browsing experience. However, sometimes caching prevents you from seeing updates to a web page.

Luckily, all of the popular web browsers provide ways to manually clear your cache. Click on your web browser below to follow the individual steps.
