In short, Internet Explorer is no longer considered a modern browser. This is because modern browsers keep up with the changes that are constantly happening within the Internet. Chrome, Firefox, Edge (which is Microsoft’s replacement for Internet Explorer), and Safari are all releasing new versions and updates that accommodate the technologies that is being released. Microsoft is not maintaining Internet Explorer by keeping up with these new changes. We recommend discontinuing use of Internet Explorer as your browser. Some of these issues you will not notice because you simply don’t know what you don’t know (meaning sometimes something doesn’t show on Internet Explorer while it does show on all other modern browsers).

(It may SEEM to say they update it but… Scroll to the bottom and read the last paragraph) They say: “We’re not supporting new web standards for it” which means they are not keeping it up to date with the latest changes that all other browsers are maintaining, which means that there would be plenty of things that will not work properly in Internet Explorer.

Microsoft stopped supporting versions 7, 8, 9, and 10 of IE back on Jan 12, 2016. That means no patches or security updates, which makes your PC more vulnerable to viruses and malware. There are also no more features or fixes, which is bad news for software that has such a long history of bugs and oddities.
