In this article, you will learn why we no longer support the use of Internet Explorer (IE) 11 with our platform and what browsers to use moving forward.
As of August 31, 2021, Dispatch will no longer support using Internet Explorer 11 to access the Marketplace App. Placing an order within the Marketplace App will not work properly if you attempt to use IE 11. We recommend switching to one of the following supported browsers: Google Chrome, Microsoft Edge, Safari, or Firefox.
A Microsoft blog post discusses the risk of using IE 11 versus using another browser such as Edge.
"Not only is Microsoft Edge a faster, more secure and more modern browsing experience than Internet Explorer, but it is also able to address a key concern: compatibility for older, legacy websites and applications."
