Internet Explorer (IE) is no longer being supported by Microsoft
If you are experiencing issues opening HTML5 content from the BRAVOzone in Internet Explorer (IE) we suggest you switch to a different browser. Microsoft will end support for Internet Explorer 11 across its Microsoft 365 apps and services this year on August 17th, 2021. Internet Explorer 11 will no longer be supported for Microsoft's online services like Office 365. IE simply supports fewer and fewer modern web standards. HTML5 is a modern web standard that IE is poor at supporting. But it's not just HTML5, here is an article from Microsoft, titled The perils of using Internet Explorer as your default browser.
Microsoft's suggestion would be that everyone moves from IE to Edge browser. To prepare for IE's end of life, they introduced "Compatibility Mode" for Edge, so that legacy sites that need IE can be run while using Edge as the default browser. But until everyone moves to Edge, you or your IT team can configure IE to force modern web pages to open in Edge.
