Internet Explorer oldest browser in the market and remain forever, as per the current statement of Microsoft they improve Edge browser but keep Internet explorer forever https://www.wired.com/story/microsoft-edge-browser-chromium-internet-explorer/ .
When we talk about IE browser and their version, I remember in starting of my career we used to test application on IE 8.0 then moving forward to IE 9.0 and so on. But on other side of the coin developers dislike Internet explorer, for this they have many reasons.
I still gamble, Tech people who are working on website development industry, and try to run the application on IE 8 It won’t work, moving to IE9.0 same application struck, IE10.0 some features and so on. So, what we are doing over here, when we are not providing the good running application to user, then we say sales got down, people are moving to another platform, A/B test does not work’s well and many more explanations. If you do analysis of your application statistics, you will get to know that 40% users are using IE browsers and their version.
Dot.Net/ JAVA/ REACT based application are today's trend but moving towards the fastest technology and giving a back seat for IE browser will not increase your revenue. So, start fixing the bugs or discuss with your stakeholders and give them the insight of cross browser functionality importance.
