My current application is used by our Sale reps nationwide. Since Sale associates only use IT managed computers and our IT Department only supports IE 10,11 (Not Edge) and chrome. I only have support IE and Chrome.
It's still frustrating when things work perfectly in chrome, then everything explodes in IE. Things like Local Storage, page rendering, onloading, and CSS/Style are implemented differently in both platforms. Its a compromise trying to realize requirements on both. I often have to talk to the Bussiness Analyst and amend requirements based on this compromise.
While I was writing this, I got an email from my team telling me that our styles are not working in IE! -_-
